Abstract: The present invention provides an improved trigger return spring system via an interchangeable, replacement gun trigger return system mechanism for use in firearms, particularly a Beretta® Model 92/96 series firearm and similar firearms. The interchangeable, replacement gun trigger return system comprises a trigger return pin having a first end and a second end, a trigger return cam having a first cavity adapted to receive a trigger bar and a second cavity adapted to receive the second end of the return pin, and a spring. The invention includes methods of replacing the existing, factory installed spring, as well as using the present invention in originally manufactured firearms.
