I'm putting this here rather then the gunsmithing section as I'm curious if anyone's encountered this before, versus how to fix it.
So a friend asked that I do a little light work on his M19. Nothing crazy, polish the trigger rebound slide, change the rebound slide spring for a lighter one, clean the internals while I was there. Nothing involving tools, files, etc.
Prior to popping open the side plate I ran about a box of 50 standard pressure Speer Lawma .38 Sp rounds through just to see how it shoot. Stock trigger bascially, but by the time I got the end of the box it had a noticeable heavier trigger pull. I figured it was simply a lack of cleaning and lube on the crane, as he said he hand't messed with it in years.
So I pop of the crane and cylinder, remove the side plate and did the requested work. No biggie, nothing too dirty, just some cleaning and some lube here and there. I reassemble the pistol, and the trigger is noticeably smoother and a touch lighter. Just what I was expecting.
I ran two boxes of the same ammo (standard pressure .38 spl) through at a moderate pace, about 30 mins to fire 100 rounds total. This time the trigger started to get heavier around the 60th round. I stopped to see if anything was binding, had come loose, etc. I checked the screws, etc, and found nothing. I fired another 6, and the trigger was back to being what I expected. After about 18 more rounds it started to stiffen back up.
The first thing that comes to mind is the gun is heating up and binding ever so slightly. I didn't have any gauges with me to check cylinder gap, cylinder to frame clearance, etc. So at the moment all I've got is a hunch. Has anyone run into this before?
