I'm not new to weapons by any means, but i made my first actual handgun purchase friday. I had ordered a G30SF but it was like 6 months backordered. So i went to the store and asked the guy what he had in stock, and he handed me a G31. I liked the idea of a high velocity smaller round, so i went with it. I shot it yesterday and enjoyed it. I'm getting a G22 barrel to switch out occasionally to save $ on rounds though. I can imagine the .357sig round would be a handfull in a smaller frame.
