I traded for an AMT 1911 .45 and got a helluva deal on it because after 2 or 3 rounds the slide and frame would gall and lock up. I knew this before the deal was made so it's not like I got screwed, I just had to have it. The package included a new Bar-Sto ramped barrel and numerous top drawer aftermarket parts, about $600 total, not including the price of the gun, and I've got $215 in the whole thing. I took it apart and cleaned everything up, stoned the galled places and used 600 grit compound to lap the slide and frame, plenty of clearance here. It felt pretty smooth so I put it together with Rig Stainless Lube and went to the range. 7 rounds and it happened again! WTF? Any suggestions? Thanks.
