Sorry, I should've updated sooner as you'll all love this! I'm so mad at that gun that I've been trying to erase all memory of it.
Yes, I got all the parts in and everything. I went out to my shop and proceeded to change the trigger. With Kuhnhausen's book and the suggestions I got here it went off without a hitch. The trigger only needed a little bit of polishing to fit perfectly. I reassembled it and everything seemed to function just fine. So I went to the range...
I started off with just one round in the mag. No problems. Then I put three rounds in the mag (worrying about the full auto thing). Again, no problems. Needless to say, I was very proud of myself.
About 30 rounds later the front sight flew off.
I went to break the gun down to see if I could find out what happened from underneath. When I pulled out the slide stop, the plunger tube fell out (for the second time since I've owned it). Plungers and springs all over the floor.
I was not amused.
So I took the whole mess (what I could find) to my gunsmith and he put it back together in about 15 minutes. "Your problem" he said, "is that you're not supposed to actually
shoot a 1991". Ahhhhh!!
(he did say that my new trigger seemed fine).
Anyway, to make a long story short (shorter), I went to a gun show the next morning and traded the damn thing in on a new Kimber Classic Stainless. I'm very happy now and its' trigger is just fine as it is!
Thanks again everyone for all the Help. I accomplished the goal anyway and I learned how to do something new. Some other poor guy is going to buy a used piece of junk 1991 with a beautifully installed brand new trigger. Sigh.
