Recently started having an issue with my 1911's slide catching.
The gun itself has been properly oiled.
When the mag is removed and slide is racked, the slide returns.
When the mag is empty and in, slide is racked, the slide locks.
When the mag is loaded and in, slide is racked, the slide returns.
Problem I'm having is that pretty much after every shot, the slide catch engages and locks back the slide. Originally I thought the hammer may have been causing an obstruction, but it isn't that. On second thoughts, I figured maybe it needed oiling, so I re-oiled it entirely. Still, the slide locks back.
Any ideas?
Edit: Here's a photo showing what's going on. the slide catch is just barely grabbing on to the slide. I can't figure out why, though. Fired 7 shots, all 7 of them caught up on the slide catch like this.
