KKM barrel

[Alpha33]

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.

I 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.

Great choice I also put a 7" on my model 40 it is incredibly accurate and the velocity is on par with my Contender Carbine. You should really like this Barrel.

Barrel came today! Dropped right in with no problems. Hope the weekend isn't a complete washout so I can get to the range and try it out.

Finally made it to the range and the new barrel worked great! Tried two loads the 180 grain XTP' with 8 grains of unique and 150 grain noslers with 11.5 grains of blue dot. The empty brass looked great! No more bulge lol. I tried putting a fired case from the OEM barrel into the match chamber kkm and it only went a quarter way in. The kkm is a lot tighter in the chamber.

a huge difference to be sure, my factory length G20 KKM is amazingly accurate compared to the factory barrel
