Just got one and have a couple of questions. I put about 300 rounds through it with no failures but did notice two things. First is that the top of the magazines seem to be scarring the heck out of the brass. I guess it would okay to smooth those sharp edges down? Also noticed that while dropping a full mag with one in the chamber the top bullet will not stay in the mag, there is always a loose bullet in the handle. Is this normal? Thanks
