Hey, Im a newbie to both shooting and these internet forums, so i apologize if i dont speak the lingo. I have 5 gi mags for a 1911 and when using them the slide will not lock on the final round. I borrowed a friends Wilson Combat magazine and it worked fine. Im going to invest in some Wilson Combat mags, but i dont want to give up on the older gi mags. Any suggestions on a solution would be greatly appreciated.
