I just purchased a Springfield Loaded 1911-A1 and it has a few problems. The pistol has Novak low mount tritium night sites (3-dot) and the rear sight is mounted way left of center causing the gun to print left. The allen screw is stuck like its been welded in place. I have bent two Allen wrenches but it won't budge. Springfield said sometimes they use blue loctite and that might be the problem. I'm reluctant to heat the screw to free it because of the tritium vials. Also, the gun has a FTE about every 4 rounds with every type of ammo (230 gr ball, hydroshoks etc.). I called Springfield and they said to try different mags. I will try Wilsons and I will also replace the extractor with a Wilson Bullet Proof. I hope this is not the typical performance for these guns. Any suggestions would be appreciated.
