BRYCO ARMS
Model Jennings Nine,
9mm LUGER caliber Semiautomatic Pistol
WARNING: These pistols may create an EXTREMELY DANGEROUS CONDITION and a POTENTIAL FOR SERIOUS INJURY by firing without pulling the trigger.
During the testing of a Bryco Arms, Jennings Nine pistol by a forensic firearms examiner it was noted that it would fire upon release of the thumb safety and spontaneously fire in a FULL AUTO MODE on an inconsistent bases. When loaded with the manual thumb safety in the "safe" position, if the trigger of the submitted firearm has been pulled stiffly a few times, the firearm will discharge when the thumb safety is moved to the "fire" position.
Disassembly of the pistol revealed some wear/damage to the sear which allows slight downward movement when the trigger is pulled. It appears due to the wear/damage the sear/striker engagement is reduced allowing the striker to override the sear after the thumb safety is released.
MANUALLY UNLOADING THIS PISTOL MAY BE VERY DANGEROUS SINCE IT COULD DISCHARGE DURING THIS PROCEDURE.
