Identify the types of semiautomatic pistol malfunction that may occur
Phase 1 Clearance: Immediate action drill. Use Phase 1 clearance to fix failure to feed, failure to fire, stovepipe, and failure to extra malfunctions. The easiest way to remember this method is learn the phrase Tap, Rack, Ready, fire( if necessary). Phase 2 Clearance, if phase 1 Clearance does not clear the malfunction or the malfunction is a double feed, use Phase 2 Clearance. A phase 2 clearance is more detailed and time consuming

Often called a stovepipe, occurs when a fired cartridge case does not completely eject. The most common causes are a weak powder charge(bad ammunition), a dry weapon ( not enough lubrication), and, if while firing, the shooter does not provide enough resistance for the slide to operate( limp wrist). Use the Phase 1 clearance method - Tap, Rack and Ready-to-wear correct this malfunction

occurs when there is no powder or a partial burn of powder and the primer ignites. The result is incomplete propulsion of the bullet, which may lodge the projectile in the barrel. THIS IS A MAJOR SAFETY HAZARD.
Identify Cheek Weld
provides firm contact between your cheek and the comb of the stock. To form a cheek weld, raise the stock to your cheek; do not lower your cheek to the stock. Tightly hold the flesh against the cheekbone so it acts as a buffer. The firm contact between the head, hand, and shotgun enables your head and weapon to recoil as one unit. This aids in rapid recovery between rounds. The cheek weld lets you maintain the same distance behind the receiver, further assisting in correct sight alignment.
