I dry ran some rounds through it and did run into some issues. I have two mags for it. One I bought off ebay and the other came with the parts I got. Both work in the gun and will feed, but there are subtle differences that may be why some do and don't work. The one with the black bottom came with the parts. The silver one I bought separately. The biggest difference I found was the little hold open tab on the follower is bigger on the black one than on the silver one. The silver one feeds nicely while the black one seems to angle the rounds too far up. This may have to do with the tab. Also I notice that the rounds in the black one do not all sit at the same angle. The first one sits along the follower and the rest sit at a shallower angle than the one before it. The silver one, all the rounds sit at the same angle as the follower. I again attribute this to the tab. I know this may not mean much, once I fire it, but its a start.
