    I have seen videos on turning a Glock 32 into a G23 by simply swapping out the barrels for one and other, but I have had some difficulty finding any solid answers as to whether or not it would work the other way around (it seems logical that it should, but they say you should only down-convert and I don't know if the .357 sig is that much more to handle for a gun wear and tear wise?). Anyways, I was wondering if anybody had done this, and if so, is it bad for my 23? Will it be harder on the gun and wear it out quickly or is a .40 s&w model built to handle both cartridges? I really want to add .357 sig to my arsenal, but if I can do so while saving several hundred dollars, even better!

  2. Glock 23 and 32 are the same gun except for the barrel and the follower in the magazine.
    Factory Sig and .40 S&W have relatively similar momentum (recoil) levels and function just fine in the G23 platform. Gen4 dual recoil spring guns handle hot loads better but Gen3 guns are just fine. Very early .40 Glocks did not have as big frame rails and will show wear and tear sooner with any hot loads of either caliber.
    Replace your recoil spring as it fatigues (will depend on load) and you're good to go.

    On a side note most late model .40 magazines will cycle .357 Sig just fine but some of the earlier ones had different followers and were not as reliable.

    In short: .357Sig and .40 S&W is a super easy conversion in Glocks (and most other brands too).

    Thank you very much! One and done; I'm off to buy a 32 barrel! :D
     
  4. Enjoy! .357
    Sig is a great caliber :)
     
  5. It works great in my M&P i.e. 357Sig to 40S&W.
     
  6. If you buy an aftermarket barrel you will be able to shoot lead as well. A factory barrel mens jacketed only with the poly rifling... I have had good luck with storm lake barrels in my glocks.

    Good, the barrel I just purchased was a Storm Lake. Can't wait for that barrel and ammo to show up at my door!
