So.....
GP-100, 4" barrel. Gee Tater, I hope youre a big guy.
I have a DeSantis OBW leather holster, made for normal belts. It works if I have a jacket on. Im not a big guy, BTW. Man, thats one HEAVY pistol! But its a outstanding pistol.
I carry mine when working armed security. I use a duty belt. Nothing says BACK OFF!! like a big stainless wheelgun
. The dumb BGs dont know that Im only alowed to use lead bullet .38s.
