Dunno about the Glock, but Wolf 124gr (or maybe it's 115gr) 9mm does NOT cycle properly in my HiPower. In fact, it's the only thing said HiPower has refused to eat.
Dunno 'bout KB, though. Never had that happen, nor seen it happen, nor heard first hand of it happening.
I pumped the cheap steel cased wolf thru my Glock 19 to see what would happen. It worked fine. I have fed all kinds of ammo thru each of my Glocks, and they have eaten everything. Several thousand rounds, and not a single hiccup from any of them.
I shoot IDPA and many of the shooters use Glock 19 or 17s. No one that I talked with has ever experienced any problems. I’m sure the M&Ps are fine guns too.
My wife purchased a 1000 rd box of Wolf in preparation for a self defense class in San Diego (2000). Her Sig 225 was full of tiny metal flakes after about 200 rds. It was jamming. I purchased some high quality 9mm brass and loaded up some 124 gr that perfectly cycled the Sig 225 for the remainder of her class. No problems with good quality ammo. We've been feeding the Wolf stuff to her Ruger PC9 rifle. It works fine there.
How old is you HP?
I bought mine back in 1980, and its feed ramp is a little steep, so other than full ball 115gr ammo, it doesn't feed very well. I suppose I should have had a smith take a look and mod the ramp long ago.
Now my Browning BDM on the other hand, has a voracious appetite and eats just about anything I've tried.
Thanks-
