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! Wanna kill these ads? We can help!
