I have read about some feed problems and believe it is due to the magazine problem. I cycle all my ammunition through the gun before I carry it for defense (plus a whole lot of anything). I am having trouble have the shell cycle into the chamber smoothly. I get hangups where a shell try to feed (half out of the magazine) and a shell is hung on the slide. I put a 1/4 of a drop of gun oil on the feed and checked the magazines but have the same problem. The magazines are factory. I have not yet had it hangup while shooting but if it is a problem I want to fix it. Thanks.
