Carefully inspect your ammunition. Immediately refer to a qualified gunsmith if the striker indent on a fired cartridge's primer is light, off-center or does not exist. Following the "FIELD STRIPPING" instructions, (pages 28-30), field strip the pistol and look down the barrel to make sure that no obstruction exists. If a barrel obstruction is detected, a qualified gunsmith must remove the obstruction and inspect the pistol before it can be fired. WARNING: If another cartridge is fired into an obstructed barrel, catastrophic failure can result. WARNING: If, while firing, you hear a change in the sound of a fired cartridge, or feel a change in the amount of recoil, or detect any other irregularity, CEASE FIRING IMMEDIATELY and do the following: Keep the firearm pointed in a SAFE direction. A "squib load" may have occurred. A "squib" occurs when a cartridge fires, but with insufficient force to drive the bullet out of the barrel. This can result in a dangerous bore obstruction. With the gun pointed in a SAFE direction, completely unload the firearm by following the 'UNLOADING" (pages 15-17). Following the "FIELD STRIPPING" instructions (pages 28-30), field strip the pistol and look down the barrel to make sure that no obstruction exists. WARNING: Never attempt to reuse or fire ammunition that did not fire the first time. Dispose of unfired or damaged ammunition properly, per the ammunition manufacturer's recommendation. 19
