New to Recreational Handgunning
I am new to this forum and new to recreational hand gunning (actually haven't started yet as I am shopping for the right gun). I am in the military and shoot handguns every now and then but have really become interested in purchasing my own and shooting recreationally and may be some day competitively (who knows). I have been researching the XDm series and really like the looks, the functionality and the design. I am not sure which caliber I want but looking at either 9mm or .40. Can you guys help me out with the possible pros and cons of the two calibers as a beginning gun?
