Hey guys I'm new here.... and new to owning a firearm. The store I bought my gun from has a range down stairs so we took the gun from the case and fired about 90rounds thru it. Now I am using some of the cheapest ammo I could find at Wal-Mart. Trul-ammo 115gr FMJ brassmax.. im having an issue where its FTF u can tap the slide and it will close up. I have tried the magazine fix. I haven't polished the feed ramp.
