I have a duotone Pt1911 which has maybe 1k of rounds through it. I have a wilson bushing compensator installed on it. When I went to the range I noticed the safety would no longer engage... meaning the slide did not go far enough fwd for it too slip behind the groove in slide. I field stripped it down expecting to find a buildup somewhere and did a thorough cleaning. When I reassembled it it was still the same. I took out the bushing and when I pushed slide fwd enough so safety would engage the barrel slants downward at the end of the barrel more than the bushing would allow. When the bushing is installed (even tried the original factory bushing ) the slide will not move far enough fwd to allow the safety to slip past the slide. Except for the compensator and firesights it is stock. The safety worked up until this range trip. I filed off about 1/32" of the safety tang and it will now engage . Any ideas ? Why would pushing the slide all the way fwd cant the bbl all of sudden ? By all the way fwd ... i mean about 1/64" more than with the bushing installed.
