Hi, I didn't want to hijack EMC45's thread about his contender popping open when fired, so I started this one - my contender won't open.
If you just lightly close it (empty chamber) it opens pretty well, but if it gets closed sharply it takes two hands to open it. Seems as if the locking lugs are wedging into place tightly, and getting pinched so they won't release. FWIW it's a early frame with a .22 rf barrel with the split locking lugs (maybe G2).
I tried polishing the ramps on the trigger housing that retract the locking lugs, and the top of the locking lugs, but it didn't help much.
