I'm not sure what pistol to use. Minor or major? I already have an XDm in .40 and a G23. I think these would be classified as major? If I shot major I might as well shoot with one of my 1911's or my HK USP45(although reloads would not be friendly considering mag release placement). Or better to buy a G17 and shoot minor? I have no 9mm pistols. Thoughts and advice?
