Spent a little time this morning fixing some stuff in my PT1911. A few years ago I bought a used one on GB that was supposed to be 'like new' but when I detail-stripped it, it had carbon and gunk inside from about 500 rounds. Whatever, it was cheap but had some really nice features, like great barrel fit, beautiful polishing inside, fine 90-degree checkering, etc. Naturally I started right in on it, taking out the FLGR and putting in the standard G.I. guide rod and spring plug. Both sights were adjusted to the left, so I guess the previous owner sold it because he couldn't correct it from shooting right even though he shifted both sights left.
I took it to the range and sighted it in.
Then I went hog wild and refinished it and added new grips (Brownell's Teflon Moly Oven Bake). I installed night sights and sighted those in. Then I screwed up - I took it to the gunsmith at Gander Mountain to have a new hammer, sear and single safety installed. It functioned, but he put a really stiff mainspring in it so it was hard to cock, and the trigger was way too light, 3 lbs or less - a 'hair trigger'. Well, I didn't shoot it much after that and I was thinking about getting rid of it, but felt like I had to make it fully functional first but didn't want to spend any more on it. That led me to do a little research. Then I went ahead and put the original mainspring back in, adjusted the sear spring tines and got a 4.5 lb pull. The recoil spring was a little short so I put a new one in. Then I took some time and cleaned/lubricated the whole thing.
Bottom line, I decided to keep it and I can't wait to shoot it again. It was very accurate the last time I shot it, dead on at 15 yds.
