I have a Glock 31 and want to convert it to a 40 s&W for ccw purposes. Is everything identical between the two other than the barrels and caliber markings? I want to ensure the factory glock reliablity. I am getting a glock factory g22 barrel.
just the barrel, everything else works just fine. The base of the 40 in the same as the 357 sig no no functioning problems. Just make sure the 357 mags feed fine (i've always used the correct mag, but i may be anal retentive on that) or get 22 mags.
