Received my single shot loader for my Crown yesterday from Carm magazines. Upon sliding it in, it only went in a quarter of an inch and bound up. Ended up using a fine file, then my hand held vibrating sander on the slot side to get it to fit. Ended up taking about .007 off, a bit snug, but works as it should. Also checked the magazine slot on the Crown to make sure it was concentric, which it was. This was not a big problem, made it work, just wondering if anyone else has had fitment issues. I did send a email to Darko explaining the problem, along with the Crown slot dimension, hoping he will address this. Thanks Rick
