3. Irregular or unusual sound during firing If, while firing, you hear a change in the sound a fired cartridge makes or feel a change in the amount of recoil of a fired cartridge or detect any other irregularity: CEASE FIRING IMMEDIATELY! • Keep the firearm pointed in a SAFE direction. A "squib load" may have occurred. A "squib" occurs when a cartridge fires but has insufficient force to drive the bullet out of the barrel. This can result in a dangerous barrel obstruction. WARNING: If another cartridge is fired into an obstructed barrel, a catastrophic failure can result. • With the gun pointed in a SAFE DIRECTION, COMPLETELY UNLOAD the firearm by following the unloading instructions. (See page 25.) • Using the disassembly instructions check to be sure there are no obstructions in the barrel. If a barrel obstruction is detected, qualified personnel, such as a gunsmith, must remove the obstruction and inspect the firearm before it can be fired. SETTINGS WARNING: Always be certain that the firearm is unloaded and the empty chamber indicator installed. Please refer to the instructions given in the "Load Check" portion of this manual.
