Out of 100rds.. I prolly had 7-10 times where the slide locked back.. and didn't feed the next shell.
Really, that is not ok. You may want to try a different magazine and see if that eliminates your problem. Usually, this is caused bybullet catching the slide stop. Sometimes this is shooter bumping the slide stop. Be sure you are not touching during recoil. It should never do this of course.A gunsmith can repair fairly easily.
