When I bought it, it was rough. I've never handled a smooth GP100 out of the box, so no big deal.
I did a trigger job and added shims (first time for that), which I thought smoothed it out quite a bit. Then I installed new sights, and to finish off I added an Altamont wood panel and rubber grip. It looked good, the action was better (though not as nice as my other GPs which have had less work), so I was pretty happy. I figured it'd smooth up more with use.
After a break from shooting it, I came back to the gun. The trigger was terrible. Heavy and gritty, and thoroughly unacceptable. But nothing seemed to be really wrong. I decided to put lighter springs in, and ordered a spring kit. It came, and I installed a 10# trigger return spring, and 10# hammer spring. It felt really nice, so I put the grip back on.
Whoa! The DA trigger is again gritty, rough, and heavy! The SA hammer pull is the same way. I took the grip off to inspect it yet again, and everything is suddenly back to being smooth. Then I notice the wear on the grip screw.
The hammer strut (which is, and has, been installed correctly the whole time, and yes I did check) has been running across the grip screw, causing drag and grinding the surface of the hammer strut.
I ended up putting a few drops of oil on the end of the hammer strut (to help it polish itself back out on the strut retaining bracket), and installed a Hogue grooveless monogrip. It''s smoother than it's ever been, and hopefully it'll stay that way whilst still setting off every primer struck by the firing pin.
Of all things, a grip screw was the problem with the action. I never would have guessed.
