I picked up a new in box 20 year old M15 (S&W Heritage series with Turnbull color case hardened frame). The double action pretty much sucked out of the box.... Yes, I am a heathen and I am shooting it..... When I took the factory grips off to wipe it down I discovered some light rust. That helped me rationalize shooting it.
I slicked up a few burrs inside, put a 14 pound rebound spring and a different factory mainspring in it. This work has dramatically improved the trigger pull. As has firing and dry firing it about a thousand times.
But, since new, the final stacking portion of the pull, where you could stage it, is much more of a creepy, hard, increase in pull than any other Smith I have had. I am wondering if this could be insufficient clearance between the DA sear nose and the trigger?
Thoughts?
