Ugh. I spoke too soon.
I was home at lunch and decided to swap out the parts real quick, and apparently I was in too much of a hurry. I was driving out the pins when the punch slipped and left a big gash down the side of the frame. This gun has a Polycoat finish instead of blueing so I can't even touch it up.
My ham-handedness got the best of me a second time when I was replacing the sear. Like an idiot I decided to switch out just the sear rather than swapping the entire sear cage assembly, so I took it all apart. Inside there is a tiny little spring, about 1/64" diameter wire, that connects to the lifter for the firing pin block. It's under pressure so you have to be really careful when taking it apart. I wasn't careful enough and it went flying across the room somewhere.
The gun won't fire without that spring, so it's either cannibalize my 75 Compact or not shoot this weekend. I was so frustrated I just left it in pieces on my workbench and went back to work.
