I went with a XD9 sub compact. No gripes though I wish I would have gone with a .40 or .45. Granted I am sure it will not have any issue stopping someone unless they are hopped up on some bath salts or something.
Meh, modern day ammo makes the 9mm a totally viable self-defense round. Gold Dot or HST 124+p or 147gr is my primary choice for carry. I have some Gold Dot 115 +p+ and Ranger 127 +p+ as well. Don't get me wrong, I love the .45 ACP, still my favorite handgun round but no worries with nmy 9's. I have an XDM45 and had an XD9 sub compact, great gun as I put over 6000 rounds through it with one failure that I could blame on the gun.
