So far I've run over 600 rounds of various types through my LC9, and give it a good cleaning after every trip to the range... and until now haven't had one problem. Found Winchester white box at Wal-mart, and thought the $26 / 100 price too good to pass up. After less than 50, THREE hang-ups... had to tug the spent brass out with a pocket knife. Blew two mags of my "carry" ammo (Hornady Critical Defense) with no problems just to make sure I didn't have a big problem on my hands. Anyone else had this kind of problem? A friend said it was because I was lubing with gunoil instead of grease, and that's on my shopping list now... but it's not like I don't make sure it's clean and oiled before I head to the range.
