After a recent success with fitting an Ed Brown semi-drop in barrel to a Springer, and getting good results at the range a friend asked if I would fit one to his Springfield, like an idiot I agreed. As usual it was a very tight fit and the barrel needed thinning just below the upper lug area and the. Now the problem is that when the slide is racked back the chamber end of the barrel is not resting on the frame bridge, its almost there, just maybe a .015" gap (still feeds FMJ OK). When the slide is removed and the barrel attached with just the slide stop pin the barrel can be pivitod back and forward and rests perfectly on the frame bridge. Now where the hell do I even begin to resolve this? Thought the lower lugs were too long but if that were the case it wouldnt rest on the bridge as it does when the slide is removed. Maybe its binding up at the Ed Brown barrel bushing? Is this common or maybe its nothing to worry about however the gap between hood and slide lug area is no where near the .020 that Schuemann advise, more like .005 so there is a little drag in that area. Why did I get involved?!!
