Introduction
• Head Instructor• About the Club• Student Introductions
Class Information
• Need ID & Writing Implement• Focus on Competitive not
Defensive• Satisfies State Safety
Requirements– Certificate to get a LTC or FID
Pistol Components
• Barrel– Front end where bullet exits
• Frame– Backbone where everything is
attached
• Action– Moving parts: load,fire, and unload
Pistol Concepts
• Double-Action– Pulling the trigger cocks then releases
hammer
• Single-Action– Pulling trigger only releases the hammer
• Hammerless– Hammer is not visible (internal
mechanism)
Pistol Types
• Revolver– Distinctive spinning cylinder to hold
cartridges
• Semi-Automatic– Uses the power released by the action of
firing to load the next shot from the Magazine
• Fully Automatic– Same as above, but continues to fire while
the trigger is pulled
Ammunition Types
• Huge Variety• Most common pistol:
– 22long rifle, 9mm, 45ACP
• Large calibers are Centerfire• 22lr still dangerous
– 12000PSI– 1 Mile
Smith & Wesson Model 41
• Semi-Automatic 22lr• Breaks down easily• Problem with Triggerlock• Adjusting sights with pennies
– 1/8” click elevation(50ft)– 5/64” click windage(50ft)– 12 clocks per turn
S&W Model 41(cont)
• Disassemble• Parts:
– Extractor, firing-pin– Slide-stop/ejector, trigger guard,
hammer, safety, fore & back straps• Magazine vs Clip
– Clip does not have contained spring• Demo feeding without barrel
Mechanical Safety
• A safety on a pistol is designed to reduce accidental discharge
• It can fail – don’t trust it
Golden Safety Rule
• Always treat the gun as though it were loaded, even if you know it isn’t.– Other factors can change the state of
the gun without your knowledge
• Dummy plug– Verify unfireable from a distance
Safety Rules• Always keep the gun pointed in a
safe direction• Always keep your guns unloaded
until you are ready to shoot• Always keep your finger off the
trigger until ready to shoot• Know your target and what is
beyond• These rules apply to Air Pistols also!
Cease Fire
• Stop Shooting Immediately• Remove your finger from the trigger• Keep the muzzle pointed in a safe
direction• Wait for further instructions from
the Range Officer• Anyone can call a “Cease Fire”
Lead
• Lead is Toxic if ingested• Wash hands before eating• One fatality known since 1820’s
– Don’t eat/drink on the range!
Eyes and Ears
• Gun discharge extremely loud– Esp. in enclosed spaces
• Wear Hearing protectors or Earplugs
• Wear Eye protectors– Flying brass
Shooting Fundamentals
• Natural Point of Aim• Grip• Breath Control• Sight Alignment• Trigger Squeeze• Followthrough
Natural Point of Aim
• Find dominant eye• Find comfortable position
– 45 degrees is good start– Feet at shoulder distance
• Hand points at the center of the target
• Lock wrist and elbow• Move back foot to adjust angle
Grip
• Grip should be firm– Not limp nor crushing
• “Holding a child’s hand”
– Consistent• Memorize how it feels• Non-shooting hand to adjust
Breath Control• Hold breath while making the shot
– Reduces body movement• 8-10 seconds before losing visual
acuity• Take deep breaths to slow down
heart-rate• Take a breath while lifting the gun• Let out small amounts of air to
adjust vertical position
Sight Alignment
• Demo with Sight Toy• Focus on the front sight with Dominant
Eye!• Tops should be even• Front sight in the middle of the notch
– Equal spacing on both sides
• Point of Aim– Center hold, 6-o’clock, sub-6, line of white– 8” sight radius: 1/16” = 5” at 50ft
Trigger Squeeze
• Smoothly• Straight to the Back
– Without disturbing sight alignment
• Finger placement• Dry firing
Follow through
• After making the shot, re-sight it• Hold it (1-2 seconds)• Call the shot• Minimizes unneccessary movement
before bullet leaves barrel• Build muscle memory and tone
– Rapid Fire training
Sight Adjustment
• Rear Sight in direction to move shots– Shooting high, move sights higher
• German “bei” means “if”
Ammunition Components• Case
– Precise brass container• Primer
– Senstive to shock• Powder
– Nitrocellulous aka. Smokeless Powder• Bullet
– Usually lead, sometimes with brass coating
Gunpowder
• Burns Fast and Produces Hot Gases
• Exponential Speed as Temperature Increases
• Demonstration• High Pressure Loads (+P, +P+)
Malfunctions• Misfire
– Fails after primer struck by firing pin
• Hangfire– Slow ignition
• Keep pistol pointed in safe direction 30 seconds before clearing the “dud”
• Squib load– Underpowered– Check for blockage in barrel
Cleaning
• Clean each time used• Make sure:
– Unloaded– Action Open– No Ammunition nearby
• Clean from rear to reduce muzzle wear– Avoid denting crown
Storage
• Need to be inaccessible to unauthorized persons– Trigger Locks– Gunsafes– Locked Boxes
Transportation
• Laws vary• Ask local law enforcement or legal
counsel for specific rules and regulations
