I brought my brand new G27 out to the range tonight to do some firing. I only had one mag with me so it was a quick trip for sure. After firing off 5 rounds I shot the 6th round and the slide stayed open much like it would had the mag been empty. A simple pull backwards on the slide chambered the round and all was fine. this happened on my 6,7,8 shot. I'm shooting with Winchester 180gr FMJ's.
Any ideas on what's going on? Should I have the gun checked out? is it because it's the first time shooting it and it needs a break in period? or is the ammo?
any advice would be appreciated
