I got some mad money I am wanting to spend from Christmas. I currently own a 40 full size M&P and was debating on getting one in the C model. I also am kicking around the idea of a pocket pistol, like the Kel-Tec PF9. How much of a difference in size is the full size vs the C model. I know, it not going to be in the pocket pistol range, but would like to hear about it.
