How tight can you make a 1911 without effecting reliability? I swapped a "drop in" Storm Lake into my Springer Loaded and it's pretty tight. A good snap on the slide will open it up. It's nothing like stock though. I haven't gotten to shoot it yet.
If you have to "Pop" it to get it un-locked you might be an the tight side. Cycle the slide and put the barrel into battery. Push down on the back of the barrel "Hood".....if it drops at all there is more work to be done.
Even a drop in barrel needs to be fit up sometimes.
