1. IF you want to shoot reloads in ANY Glock..get a replacement barrel that has been properly heat treated and you will have NO problems. All the after-market barrels except Glock are good.
2. HSM is JUNK ! period. I don't care if Cabellas is DUMB enough to sell it.
In Colorado, they just lost ALL their LE from Blowing up a BRAND NEW Colt M-4 223 in one PD and an entire County Contract from 45acp and 223 that either would not chamber or function reliably in 45acps from Colt 1911 's to Les Baer 1911's. They have little quality control. They could not get thru a mag of HSM 223 without a jam.
They HAVE been around for years and I have sold hundereds of thousands of
rounds of their ammo in the past 25+ years in the business. NOT now...is it not safe to shoot. We examined many rounds from a Sheriff's Department and the velocity varied over 100FPS round to round and the OAL length varied far too much.
