I have a glock22 .40Cal, Wat do I have to change to allow me to shoot 9mm or .357 sig? Should I just order a barrel in those calibers or does it have to be an actual "conversion" barrel?
You can shoot 9mm from the .40 Mags. I've been doing this for months and not one problem.jonm61 said:For the .357Sig, you can just buy a barrel, even an OEM barrel from Glock, and use your existing magazines.
As far as the 9mm, everything above is correct. It has to be a conversion barrel, as they are made to the same OD as the .40 barrels and you have to use 9mm magazines. As far as the ejector, if you're only shooting the 9mm for target practice, then leave it alone. If you're considering carrying the gun with a conversion barrel, don't. You could have both extractor and ejector issues and you do not want a failure to eject when you need the gun to function flawlessly. You might fire 10k rounds without a problem; but if it fails once when it counts, that's all that matters.
