I actually found a video on youtube regarding how to remove and install the trigger/internal assembly for a CVA, so I decided to follow along to give these not-yet-fired- CVA's a simple trigger job:
CVA Optima Trigger Assembly ISSUES, a simple fix!
Made the pins out of brass:
Soon I had lots of parts in my bench (here on top you can see pieces for the work-in-progress for my low back-pressure, user-adjustable F1 suppressor):
I didn't touch anything with a stone/file - I only polished the two mating surfaces - here the trigger:
I had the video with me on the bench so that I can follow along:
What the video does not say, is that the lever to open the single-action has to ALSO engage an internal portion to act in releasing the barrell. You can fairly easily put everything back together (with the aid of the two pins - otherwise impossible), but it took me like 5-10min of trying to wiggle that lower assembly until I can catch that inner piece, which also is under spring pressure - you almost need 4 hands to do everything. No wonder the factory uses some type of jig!.
Of course, once I finished with the 300BLK, I did the 35 Whelen as well. The trigger pull is certainly a little lower and smoother on both now, specially on the 35 Whelen - that one end up being a tad lighter.
