Glock 20 SF, factory length Storm Lake Barrel, 22lb non captured wolf spring. Started working up some hot loads for my gun. Got into some malfunction with my loads. Loaded 10 rnds in a mag. First 4-5 rounds would not be picked up by the slide. Bullet appears to not of been pushed up fast enough by Mag spring. So first question is, do you guys run Xtra power springs in your mags, for reliability? Ran some other stuff thru the gun today. Not sure if they were reloads or what. But every round hung up going into the chamber. If I then pulled the slide back 1/8", and let go. It would feed the round into the chamber. I'm thinking maybe the crimp? Anyone having problems with Storm lake barrels? Maybe my reloads aren't up to snuff yet, I don't know. But I am considering going back to the stock set up, for better reliability. Any ideas?
