I currently have a G21 and a G36. The G36 is my daily carry and my G21 is my nightstand gun. Im going to be receiving my next GSSF coupon soon and need some guidance in which way i should spend it. G19 would fit into my G36 holsters from what Im told, and that would make for a great alternate daily carry. G30 would complete my 45acp Glock collection and with a 9 round baseplate would make a great alternate for daily carry as well but would require a new holster (unless I make a G30/36 hybrid from what Im told). Any help would be appreciated.
