Pauly, Nice gun and excellent cartridge.I contacted Glock about a 357Sig barrel for my M-27.They told me I just needed to change the barrel,that it uses the 40cal mags.I' m sure it would be the same on your gun.I wanted to convert my M-26 before I traded it off but the 9mm couldn' t be converted to the Sig cartridge.You' ll get many good years of shooting out of tha Glock.
