I have a DB9 (Diamondback firearms) and it is small, comparible is size to a SIG P238. While I have some current issues with it feeding, it is getting better, but it is painful to shoot. I have figured out how to shoot it so it's not to bad, but still not a fun gun to shoot. I think it weighs a little more than 12 oz. empty, so it is a very pocketable 9mm in that respect. It may not quite be as small a R9, but it is lighter being a polymer framed pistol. In the end, I don't think I'd want anything lighter than a DB9 or smaller than a R9. LM
