Lloyd, the next time you have a full size 1911 that isn't running right, give Bob Rodgers a call. After he does a reliability package on one it will run and run and run.
I had this series 70 Gov't which I didn't care for
and I sent it off to Bob for a make over. The steel in the gun had pitting under the factory finish which is probably from the base metal plating or something reacting with the steel of the slide & frame so it couldn't be hard chromed and look good so it got this finish instead.
Bob shows this gun on his website.
I took it out once, loaded up
ALL my magazines and fired 400 rounds through it pretty much non stop. It got a bit warm (maybe an understatement), my steel targets begged for mercy and it never missed a beat. I've heard of several pistolsmiths that do really top notch work but my experience has been with Bob initially at the recommendation of Chuck Rogers. Bob's work is the best and once he has fixed a gun for me it runs the way it should.
I can post a link to his site but I'm not sure it's allowed here and I don't want to run afoul of the rules.
