After performing any work on your firearm such as cleaning, disassembly,
or installation of any accessory, check your firearm for proper functioning
before firing any live ammunition.
Firearms are complicated mechanisms. Any modification, alteration, or
improper fitting of parts may result in a dangerous malfunction, damage
to the firearm and injury to the shooter and others. The firearm’s owner
is responsible for the correct reassembly and functioning of the firearm
after any disassembly or replacement of parts.
Visually and physically inspect the chamber and bore of the barrel to
make certain it is free of any obstructions, excessive oil or grease. If you
are unable to remove any obstruction, bring the firearm to a qualified
gunsmith or send it to a factory authorized Product Service Center.
Obstructions of any kind can result in damage to the firearm and/or serious
personal injury to you or those around you when the firearm is fired.
