Quote from: Goetztalon on June 02 2018 03:41:22 PM MDTI use a 6" threaded kkm for my glock 20, hunting and woods defense. We live in Ouachita Mountains, 60 acres all sides surrounded by National Forest. I have found you get occasional jams with the 200 - 220 cast slugs. Running them through a sizer helps, but not 100%. I'm talking 1 or 2 in 50 will not feed completely. Usually you can palm the back of the slide and it will seat. The problem usually starts after 20 or so shots and progresses. My guess is the chamber is tight and probably gets some lube or lead build up as the shot count rises. Not frequent, but not what I want for woods defense! Now I use Lehigh Xtreme Penetrator slugs over Longshot powder getting 700 fpe for bear defense. Whistles through level 3 vest, right through bullet proof glass, but still disrupts tissue. It and all jacketed or plated bullets are 100% reliable in the kkm.
Ordered a six inch kkm barrel for the Glock 20 yesterday. Now I will be legal for Ohio's five inch minimum barrel length to use a hand gun for deer. Anybody have any opinion s on the kkm? Did some online research and it seems to be a decent barrel.
