Just a note, if you happen to have an Armscorp aka Rock Island Armory 1911a1. Shot 50 rnds of no name ammo thru mine in Nov, and did a detail strip n cleaning. And had all sorts of problems putting the damn tight thing back together, The receiver would not pass the safety checks, either the hammer wouldn't half or full cock, or the grip safety wouldn't work right. Finally got it to work, but I did notice this:

Depending on my first attempt at attaching a file pic, and sorry for my poor digital camera work, the surfaces where the sear mates with the hammer, are slightly rounded. Looks like Armscorp used MIM (Metal Injection Molding) to make the unfinished hammer and then did a minimum of machining.

When the lower is properly put together, the safety and sear and hammer do work together, but the rounded surface annoyed me so much, that a week of waiting for parts from Sarco and Numrich, and a trip to the local 1911 Wizard and $20 later, I've got a N.O.S. hammer and strut in place.

So, if you happen to own a RIA 1911a1, take a close look, you might want to make a change.
