Colt NRM 1991A1: What are the possible culprits that could stop a slide from locking back? I thought I had resolved the issue when I switched to the Wilson Bulletproof slidestop, but while shooting today it failed to lock back with three different mags. I was shooting seven different WC 47D magazines and it failed on three of them. On the third failure I stopped shooting that pistol and went back to my LBC TRS, which ran perfectly with all seven Wilson mags even though it's still too tight
So what is the most likely issue? The slide stop installed is a new WC BP which I feel good about. I may try a different Colt slidestop, but I really don't think the slidestop is the issue. It did the same thing with the original Colt factory slidestop so I'm looking for other issues.
How about the plunger? Could that stop the slidestop from moving up? What about the plunger would cause this effect.
I noticed some copper on the slidestop where it protrudes into the magazine. Is it protruding too far? Is that even an issue? I have a nice set of files if that's the case, but I would think that copper would tend to push it up early rather than not let it move, particularly after the last round is gone. TIA
