I'll be purchasing a 9mm as a present to myself when I return from my deployment. Obviously most everyone here would recommend the XD or XDm. I'm just wondering what people's thoughts/opinions are on the full/compact/sub-compact sizes. I plan on using this as a second carry, in addition to my S&W SW99 .40, not so much as a BUG, just an additional weapon. I'll be carrying it on the Beltster.
