I have several Glocks and all seem (with some exception) to have pretty interchangeable parts. With Sigs you are able to buy parts kits from Sig /Midway/Top Gun etc and have some spare replacement parts on hand. I have not seen any " Glock parts kits" with a little bit of everything in them for emergency repair. Does anyone know if they are available and where? PS just picked up a Model 32 G4 and love it. Buying what ammo and extra mags I can for it, as I don't have a real warm feeling on what may be coming at us from DC.
