I have a CPX-2 that I wanted to give the trigger an easier pull. Experience level is a tech,then engineer for Kodak Film Testing(anybody remember film?), reairing and designing custom apparatus., all befor a Ph.D and a university career. Most relevant is that I also replace the recoil springs and feed ramp(McCarbo replacements) on my Kel-Tech PMR 30.
The CPX firing pin spring replacement was simple. The only detour was when I punched the lever pin down and as I pulled the punch out, the lever popped out under force from the spring, with both the spring and lever hitting my chest and dropping to the floor. Re-installation at the end was accomplished with a “rubber tips” C-Clamp, holding all in place as I easily then re-installed the lever’s pin.
On to the frame and trigger spring. Frame pins. 3/32 punch, hammered the pin a few time, then a few time more. Not a budge. HArder again, till the point I was worried about frame cracking. The pin eventually move out about 3/64". *I stopped after I noticed my punch now had a slight curve in it… Quality punch from back in the day at Kodak.
Any advice would be appreciated. This is a May 2020 purchase, probably with SCCY’s oversized pins. Maybe with locktite?
