    is anyone selling the g4 barrels,have a new g4 32 and would like to get a 40 barrel for it,will the g3 barrels work in g4 guns.:whistling:
     

  2. Yes gen3 barrels work in gen4 guns. I have been running a gen3 Sig barrel in my Gen 4 Glock 23 for over a year. The only difference is the moon shaped radius on the bottom of the Gen 4 (where the base of the recoil spring sits) is very slightly larger radius than that of the Gen 3. Doesn't affect function at all.

    If you are concerned you could buy an extra gen 4 recoil assembly and grind down the diameter of the base which sits against the barrel. Don't think it is necessary though. I have had zero malfunctions in close to a thousand rounds.

    I ordered my G31 barrel from them, and the cutout was the same as my G22 Gen4 barrel. I had the same concern, and was shipped what looks to be a Gen4 barrel.

    Works like a champ, and I don't think that I'll be using my G22 barrel in that pistol any more, since that one has become my reference pistol for my .357SIG loads I make.

    Glock sells them for $125.
    I had no problem using a g3 barrel in a g4 gun, eventually I ground the tips of the half moon for a better fit. The spring rests on the barrel till the slide is installed, at that point the spring no longer touches the barrel, it rests on the frame.
