Hey guys ,I have a Glock 20 with a 6 inch lone wolf barrel that's giving me fits. 1st it was hanging up with failure to go into battery with every ammo I tried except Prv. I took the barrel out when I got home and found some burrs on the top of the chamber and stoned them down a little. A buddy of mine also suggested I try a heaver spring. I put in a wolf 22 lb spring and tested it out today. Well it went into battery smoothy but now every on 3rd shot the slide locks open with a mag full of ammo. Any suggestions.
