As my friend said, "For someone that doesn't like Glocks you are getting a lot of Glocks". G26, G19 and now a G33. I got the G33 last week and I have a few questions. Magazines? Can a 40 S&W mag be used in place of the .357 SIG mag or the .357 mag used in 40 S&W? Conversions for cheaper shooting? Anyone done this? I understand the G33 can be converted to 9mm or 40 S&W with just a barrel swap but how about the extractor, ejector for 9mm? I've seen ads for aftermarket replacement barrels for about $110. Why can't a Glock 9mm or 40 S&W barrel be used? I don't plan on doing it but would my G26 barrel be a drop in conversion for the G33?
