I bought a bunch (1000) of this ammo, since I found a very good deal online (about $15 / box). Cheaper than FMJ range ammo. It turned my G23 into a jam-o-matic. My Glocks have always eaten anything I've fed them. I tried various magazines, including some brand new ones. Every few rounds, I'd get a failure to feed (all the way). Anyone else? Thoughts?
