Safety Considerations for EveryoneSafety Considerations for Everyone

• Handle every Firearm as if it were loaded.

• Never point a Firearm at anyone or shoot anything you don’t intend to kill.

• Do not accept a Firearm handed to you unless the action is open.

• Visually inspect the chamber.

• Control the muzzle at all times.

• Don’t trust safeties on Firearms. They are mechanical devices.

Modifications to New Generation PistolsModifications to New Generation Pistols

• Modifications by a “gunsmith” to your life saving piece of equipment puts you and others at risk.

• The tampering can make the weapon unsafe and unreliable when it is pressed into service.

• Avoid advertisements that promise to enhance performance of your weapon.

Modifications to New Generation PistolsModifications to New Generation Pistols

• The modification will usually void any manufacturer warranty and the potential of total disclaimer of weapon performance and liability.

• Killeen Police Department Firearms General Order prohibits these actions and others to the Duty Weapon.

Modifications to New Generation PistolsModifications to New Generation Pistols

• The allure of dressing up one’s duty piece is enticing, but remember the purpose of the Combat Pistol, it must be a dependable, accurate and fully functional life saving piece of equipment that must work 100% of the time. It is not a showpiece, nor a conversation piece. Do not wear your ego in your holster for all to see.

Modifications to New Generation PistolsModifications to New Generation Pistols

• Your new generation pistol is the result of years of research and testing. Your weapon has benefited from the early model competition weapons and street proven techniques that were normally considered “customizing”. Out of the box, your weapon is COMBAT READY.

Modern Techniques of ShootingModern Techniques of Shooting

DVCDiligentia Vis Celerita

Latin for “accuracy, power, speed”, is the defacto motto of the Modern Technique and of practical shooting in general.

An accurate shot is useless if delivered too slowly or with an insufficient blow. A powerful blow delivered too late or which does not hit the target is likewise useless, as is a quickly delivered but inaccurate or weak blow.

The TriadThe Triad

All of the modern techniques, whether for the pistol, shotgun or rifle are based upon what

has come to be called “The Triad.”

The Triad consists of three equal and interconnected principals of gun handling, mind set and marksmanship, all of which

must be learned through proper training and practice.

Page 17: combatpistol-100130174348-phpapp01

The TriadThe Triad

• Gun Handling - This is the safe and efficient use, presentation, and maintenance of one’s firearm.

• Marksmanship - This is the ability to hit one’s target quickly and accurately.

• Mindset - This is the “crisis management” and the ability to hit one’s target while under stress. Failure to think correctly in the use of deadly force, respond to deadly force, or to learn the doctrine and techniques for their management leaves your survival or success to pure chance.

GunfightingGunfighting

The operation of weapons may be considered a science, but the use of weapons to win an

engagement is not, it is the “Art of Gunfighting”.

Page 19: combatpistol-100130174348-phpapp01

StrategyStrategy

The word Strategy derives from the Greek word “strategos” meaning General Officer. Therefore Strategy is the art of the General, indirectly to do with fighting. A good Strategist can be a poor fighter.

Page 20: combatpistol-100130174348-phpapp01

TacticsTactics

The word Tactics derives from the word “touch” and implies actually touching one’s foe in combat. Tactics has come to mean simply the more or less systematic conduct of a fight.

Page 21: combatpistol-100130174348-phpapp01

TacticsTactics

• The first principal of Tactics is SPEED.

• If fighting becomes necessary, delays of even split seconds can determine the outcome of the engagement.

• The best fight is that which is over before the loser ever realizes it has begun.

Page 22: combatpistol-100130174348-phpapp01

TacticsTactics

• No Tactical Plan is effective if it’s object is given time to understand it.

• But even a bad plan will usually succeed if it is executed before it can be intelligently countered.– Remember, a bad plan is better than no plan

at all.

Page 23: combatpistol-100130174348-phpapp01

The TacticianThe Tactician

• The goal of the Tactician is to insure that the fight is never fair. The Tactician must bring overwhelming force to bear upon the opponent and dispose of him before any counter measures can be deployed.

• This is called “defeat in detail” and both sides are aware of it. The skillful succeeds.

Page 24: combatpistol-100130174348-phpapp01

The TacticianThe Tactician

• Your opponent wants to live as much as you do, and while he may appear to be unskilled, do not count on it.– Prior training– Military– Survival School– Militia

Page 25: combatpistol-100130174348-phpapp01

The TacticianThe Tactician

• As you try to confound him, he will try to confound you. The faster of the two and the one with a plan will win.

• This is where discipline to your tactical training counts.

The TacticianThe Tactician

• Do not always rely upon strength in numbers, one skilled, alert and determined opponent can be the equivalent of a dozen men that are unskilled and undisciplined.

• Rethink numbers as units of force.

• Man fights with his mind– Hands and weapons are simply an extension of

his will.– The fallacy is that equipment is the equivalent

of force.– Specialized Teams are aware of these fallacies

and factor them into their plans.

Before the FactBefore the Fact

• You have a plan, even a bad plan is better than no plan at all.

• You have mentally prepared yourself well in advance.

• Fear and Anger are physiological responses that derive from the same chemical in your body.

Page 53: combatpistol-100130174348-phpapp01

Before the FactBefore the Fact

• When you experience FEAR, you cannot think clearly, you experience “Tunnel Vision” and have a flight instead of fight response.

• ANGER allows you to think clearly and react to the threat with decisiveness and determination.

Page 54: combatpistol-100130174348-phpapp01

During the FightDuring the Fight

• Heads up display;

• Concentration on the FRONT SIGHT;

• Smooth depression of the trigger;

• Concentration on the FRONT SIGHT.

The PistoleroThe Pistolero

• History of the Handgun– Began as a military arm, extending the reach of

the Cavalryman beyond that of the Infantry Pike, while allowing him to manage his horse with his free hand.

Page 57: combatpistol-100130174348-phpapp01

The Service PistolThe Service Pistol

• A satisfactory Service Pistol must include the following:– Dependability,– Power,– Controllability

Page 58: combatpistol-100130174348-phpapp01

DependabilityDependability

• A Service Pistol (Duty Weapon) is a life saving instrument, it must work 999 times out if a 1000.

• It must never be altered to remove factory specifications or upgraded to a “Race Gun”.

• The Officer must feel confident that the Pistol will perform when placed into service.

Page 59: combatpistol-100130174348-phpapp01

PowerPower

• It must be sufficiently powered to stop a determined threat with acceptable Wound Trauma Incapacitation (WTI).

• The larger the caliber, the more effective the WTI.

Page 60: combatpistol-100130174348-phpapp01

ControllabilityControllability

• The Officer must be able control the Pistol with minimum effort.

• The Officer must be able to perform all stoppages, clearances and reloads.

Page 61: combatpistol-100130174348-phpapp01

The SNS EffectThe SNS Effect

• Sympathetic Nervous System• Activation of the SNS is automatic and virtually

uncontrollable.• Occurs anytime one perceives a threat to survival

and results in the immediate discharge of stress hormones.

• Increase in arterial blood flow to large muscle groups, resulting in an enhancement to gross motor skills.

Page 62: combatpistol-100130174348-phpapp01

The SNS EffectThe SNS Effect

• Vasoconstriction of minor blood vessels, pupil dilation, cessation of the digestive process and muscle tremors will occur.

• Once activated, SNS will dominate all voluntary and involuntary systems until the threat is eliminated.

• Term “Tunnel Vision” and “Flight or Fight” Syndrome is used.

Page 63: combatpistol-100130174348-phpapp01

The SNS EffectThe SNS Effect

Motor Skills, Vision and Cognizant Thought Processing are the three most prominent

performance inhibitors when under the SNS effect. For these reasons the gunhandling skills taught an individual who is training for combat

must rely, to the greatest extent possible, on gross motor skills.

GripGrip

• The Grip on the weapon is the foundation of Good Marksmanship.

• You want to achieve a firm grip, but not a “white knuckle” grasp.

• Remove all the “air” from around the stocks with your hands.

Trigger ControlTrigger Control

• Control the trigger in both directions.

• Slapping the trigger produces errors in shot placement.

• Train to find the “disconnector” to allow for quicker follow-up shots.

Depressing the TriggerDepressing the Trigger

• Term is used instead of squeezing or pulling the trigger.

• Trigger depressed straight to the rear, a smooth continuous motion.

Page 68: combatpistol-100130174348-phpapp01

Establishing a Trigger RhythmEstablishing a Trigger Rhythm

• Depress trigger according to a rhythm.

• From forward most position to rear most position.

• Letting the gun go off instead of making it go off.

Page 69: combatpistol-100130174348-phpapp01

Sight AlignmentSight Alignment

• Relationship of the front sight to the rear sight without any relationship to the target.

• Light relief is obtained by extending the pistol at arms length.

• Pistol Sights are manufactured to work at arms length.

Page 70: combatpistol-100130174348-phpapp01

Center MassCenter Mass

• High Center Mass– Most effective with pistols, creates best WTI on

threat.

• Center Mass– Best used with shotgun pellets, allows for better

dispersion of shot

Page 71: combatpistol-100130174348-phpapp01

StanceStance

• Upper body strength needed when using Modified Weaver or stoppages will occur because the weapon will experience low recoil absorption.

• Lock out weapon arm firmly.

• Most any stance that closely to the Modified Weaver that is comfortable and produces good shoot placement is acceptable.

Page 72: combatpistol-100130174348-phpapp01

StanceStance

• Three dominate stances used in pistol shooting;– Weaver (classic)– Modified Weaver– Isosceles

• Turnipseed Stance– Enhanced Weaver

Page 73: combatpistol-100130174348-phpapp01

““Classic” Weaver StanceClassic” Weaver Stance

In the “Classic” Weaver two-handed stance, your strong arm is slightly flexed and pushes the gun out. The supporting arm, which is more flexed, counters this by pulling the gun in to create a strong braced hold. Sometimes referred as “Isometric” tension.

Page 74: combatpistol-100130174348-phpapp01

Modified Weaver StanceModified Weaver Stance

In the “Modified” or “Chapman” Weaver, the position of your feet is the same and your supporting arm is still flexed. Your strong arm is kept as straight as possible.

Page 75: combatpistol-100130174348-phpapp01

Weaver StanceWeaver Stance

An important characteristic of both Weaver Stances are that your feet are apart with your weak side foot slightly forward.

This is also called the “Bladed Stance” or “Interview Stance”

Page 76: combatpistol-100130174348-phpapp01

Weaver (all) StanceWeaver (all) Stance• Can stress the body if maintained for long

period of time. Skeletal alignment is unnatural.

• Has some balance control issues

• Requires discipline via training to perform this presentation under stress. Average shooter is not willing to commit.

• Experts claim SNS will force shooter into Isosceles during gunfight anyway.

Page 77: combatpistol-100130174348-phpapp01

Weaver (all) StanceWeaver (all) Stance• Good stance (oblique) for police work.

• Very fast and can deliver accurate hits.

• Blends in with “Use of Force Continuum” options.

• Allows for use of “Harries” Flashlight Technique.

Page 78: combatpistol-100130174348-phpapp01

Isosceles StanceIsosceles Stance

• The Isosceles Stance is nothing more than another variation of the Weaver.

• The weak hand is placed over the weapon side foot.

• The body is 180 degrees to the target.

• Feet placement varies from wide “Horse Stance” to leaning back to support the weapon.

Page 79: combatpistol-100130174348-phpapp01

Isosceles StanceIsosceles Stance

• Can cause stress to the body which leads to pain, fatigue and imbalance.

• Causes “overswing” of weapon to target resulting in misplaced shots or imbalance.

• Does not work with Shoulder Weapons.

• Does not blend with other aspects of “Use of Force” techniques.

• Designed for Competitive shooters to kill steel and paper.

Page 80: combatpistol-100130174348-phpapp01

Turnipseed StanceTurnipseed Stance

• Maintains balance.

• Skeletal alignment.

• Works on all weapons.

• Reduces fatigue

• Hybrid of the enhanced Weaver platform.

• Enhanced Weaver is more applicable for LE.

• Body remains loose and flexible.

Page 81: combatpistol-100130174348-phpapp01

VisionVision

• 30% of your balance is related to vision.

• During a gunfight, autonomic senses kick in and the shooter uses both eyes to pull in all the information needed to respond to threat.

• Your dominate eye will take over when shooting with both eyes open.

• You only have the ability to actively focus at arms length the size of a quarter.

Page 82: combatpistol-100130174348-phpapp01

VisionVision

• Keep sights in natural position to eye to reduce eye fatigue.

• Tilting the head causes extra work on the eye muscle groups to maintain sights in the fovea of the eyes macula (the center of the retina in the back of the eye).

• Keeping head up in a natural position reduces the strain on the eye muscles maintaining aiming precision over longer periods of time.

Page 83: combatpistol-100130174348-phpapp01

VisionVision

During SNS you will experience:• A reduction of blood flow to the rods and cones of

the eyeball.• Up to70% loss of peripheral vision.• A significant reduction in your ability to focus on

close small objects (such as the front sight).• Poor night vision and color recognition.• Binocular effect of the eye “Tunnel Vision”.

Sight PictureSight Picture

• Sight Picture is what one sees when using Sight Alignment, incorporating both front and rear sight blades.

• Flash Sight Picture is obtained by using only the front sight on the target and referencing the back sight as a window.

Page 87: combatpistol-100130174348-phpapp01

Sight PictureSight Picture

A correct firing stroke, from leather to sight picture, aligns the pistol reflexively, once it is neurologically

programmed. The sights are not used to align the pistol, but rather they are used to verify an alignment already achieved by means of a trained presentation. Your mind does not command “up, down, left, right,

that’s close, squeeze”. It simply says “Go”

Page 88: combatpistol-100130174348-phpapp01

Sight PictureSight Picture

The single most important issue with your sight alignment is the total concentration upon

the FRONT SIGHT.

As your pistol lines up reflexively from your presentation, you tell yourself;

FRONT SIGHT, FRONT SIGHT...

Page 89: combatpistol-100130174348-phpapp01

Sight PictureSight Picture

Keeping the sights aligned with each other (maintaining the sight picture) is more important than keeping the sights

precisely pointed at the target (maintaining point of aim).

Pistol Silhouette Sight TechniquePistol Silhouette Sight Technique

• Grip the Gun properly so it is a natural extension of the body.

• Focus on the threat.• Raise the gun to eye level and point it at the

threat.• Smooth depression of the trigger straight back.

Page 91: combatpistol-100130174348-phpapp01

Missing the TargetMissing the Target

• Poor grip and trigger control is usually the reason you will miss at any distance.

• Most shootings will occur in light to dim to utilize your sights.

• Night sights, flashlights are the essentials for these situations.

Page 92: combatpistol-100130174348-phpapp01

Most Common ProblemsMost Common Problems

• Flinching– Recoil– Noise– Shots string vertically downward

• Attempting to counteract the recoil

– Shots scattered• Anticipation or closing your eyes

• The Fix - Concentrate on Front Sight

Page 93: combatpistol-100130174348-phpapp01

Most Common ProblemsMost Common Problems• Jerking

– Shots strung out to one side– Pulling trigger too fast– Muscles which pull your index finger also tend

to curl your whole hand inwards.– Usually shows up when speed is added to shot

string.

• The Fix - Gradually build speed while maintaining accuracy.

Page 94: combatpistol-100130174348-phpapp01

Most Common ProblemsMost Common Problems• Fatigue

– You use muscles which normally don’t see much action, they tire out fast and performance degrades rapidly.

• The Fix - Shoot or Dry Fire regulary so your muscles will get stronger and build endurance. Fatigue will still occur, but will take longer to set in.

The Facts of LifeThe Facts of Life

• When suspects fire at LE, they hit 9 out of ten times on their target. 50% are head shots. KEEP MOVING!!!

• When LE fire on a suspect, they hit less than 4 out of 10 times.

• 92% of the time, we miss at 21 feet or less.• Average shots fired by LE has more than tripled

in the last ten years, with a reduced hit ratio.

Shot PlacementShot Placement

• Shot placement is absolutely critical. If you cannot hit the target, you cannot create WTI.

• The Term “Stopping Power” is an illusion, there is no such thing as 100% one-shot stopping power, there are no magic bullets and no substitute for Good Marksmanship.

Shot PlacementShot Placement

• Many shootings that involve Police will have intermediate, energy absorbing barriers between the Officer and the suspect.– Wood– Metal– Wallboard– Glass

Shot PlacementShot Placement

• According to the Institute of Forensic Sciences in Dallas, up to 70% of Officer involved shootings are non-frontal.

• This means that you threat will appear from left, right or rear response areas the majority of the time.

Duty Ammunition CriteriaDuty Ammunition Criteria

• There are two important issues when selecting Duty Ammunition:– Does it offer the best possible performance in a

deadly confrontation?– Will you be able to defend your decision in a

Court of Law, if needed?

Duty Ammunition CriteriaDuty Ammunition Criteria

There is no handgun ammunition which is guaranteed to stop a person with one shot,

regardless of caliber, velocity or bullet type.

Terminal BallisticsTerminal Ballistics

• Refers to Wound Trauma Incapacitation (WTI)

• What the bullet does when it enters the body and the effectiveness of the bullet to incapacitate a live human being.

Terminal BallisticsTerminal Ballistics

• Myths associated with WTI:– Shocking Power– Stopping Power– Knockdown Power

• True instant incapacitation is a relatively rare occurrence.

Terms of Terminal BallisticsTerms of Terminal Ballistics

• Permanent Cavity (Crush Cavity)– The amount of tissue actually touched, crushed

or pulped by the bullet itself and is the critical part of the wound predicting analysis at most handgun velocities.

– Big bore and expanding bullets produce the largest crush cavities.

Page 112: combatpistol-100130174348-phpapp01

Terms of Terminal BallisticsTerms of Terminal Ballistics

• Temporary (Stretch) Cavity– This temporary cavity is produced because the

bullet passage at high speed forces the tissue laterally with enough velocity to temporarily create a path much larger than the bullet.

– The kinetic energy of this moving tissue is momentarily transformed into strain energy in the elastic tissue. The bullet’s energy is transferred to the tissue losing it’s velocity.

Page 113: combatpistol-100130174348-phpapp01

Terms of Terminal BallisticsTerms of Terminal Ballistics

• Temporary (Stretch) Cavity– When the strain limit of some tissue is

exceeded, the tissue is stretched and actually torn open by the formation of the temporary stretch cavity.

– The brain, liver, spleen and kidneys are especially sensitive to stretch.

Page 114: combatpistol-100130174348-phpapp01

Terms of Terminal BallisticsTerms of Terminal Ballistics

• Zone of Maximum Disruption– The largest portion of the Temporary Stretch

Cavity.

• Penetration– The distance the bullet travels in the body– Penetration is a function of bullet weight and

design, not velocity.

Page 115: combatpistol-100130174348-phpapp01

Terms of Terminal BallisticsTerms of Terminal Ballistics

• Upset– The change of bullet shape by force or impact.

• Controlled Expansion– The designed mushrooming effect of a bullet

upon impact.– Expansion is important in that it increases the

size of the wound inflicted.

Page 116: combatpistol-100130174348-phpapp01

Terms of Terminal BallisticsTerms of Terminal Ballistics

• Energy Transfer– Energy is defined as the ability to do work.– The transfer of bullet energy to the target

causes it to penetrate, causes the bullet to expand and causes the permanent and temporary wound cavity.

– The greater the resistance, the greater the energy transferred.

Page 117: combatpistol-100130174348-phpapp01

Terms of Terminal BallisticsTerms of Terminal Ballistics

• Vital Zone– Areas on the human body containing organs or

tissue necessary to sustain life, that when struck by a bullet will likely result in physical incapacitation.

Terminal BallisticsTerminal Ballistics

• There are some things known with certainty– If the brain stem is destroyed, all ability to initiate

voluntary action is ended. If there are involuntary contractions which do not originate in the brain, movement is possible.

– If the central nervous system is damaged, movement below the point of destruction stops.

– If the vital blood supply is lost, movement will cease in a given time period.

Terminal BallisticsTerminal Ballistics

• The single most critical factor is penetration– 18 inches preferable, a bullet must penetrate at

least 12 inches, whether or not the bullet expands.

– Increased bullet mass will increase penetration.

Rapid WTI and the Human BodyRapid WTI and the Human Body

• Hitting the critical area (shot placement)– Reliable accurate weapon– High degree of shooting skill

• Effective WTI requires:– Deep penetration– Large permanent crush cavity– Loss of 40% blood or 2 quarts, strike in brain

stem or central nervous system.
