Well the STI Tactical showed up today. When i had it apart i noticed a few things. First was that the ejector didn't seem right, it wasn't flush with the rear of the slide. Taking a look, i also noticed that the ejector wasn't all the way down on the frame. Looking even closer there was no rollpin holding the ejector in. So this all adds up and shows the reason why gun gamers using double stack's modify the gun so the slide doesn't lock back on empty. My guess is that the original owner slammed a 140mm magazine in (with the slide locked back) and broke the ejector. No big deal. I installed a magazine and this is what i saw, the magazine is hitting the ejector. Blayglock told me that he was getting some feeding issues and that the mags probably need to be tuned. No problem, I've done it to my other 2011 mags. Now i'm wondering if the feed problems were actually from the rounds hanging up on the ejector. Here's what it looked like before. and after some filing. so now the ejector clears the magazine, now I need to look at my other 2011 ejector to see what other work needs to be done and then drill the ejector leg out to install a roll-pin.
