This is the only other true "pocket" 9mm- other than the DB9- that I'm aware of.
That's just it. It isn't a true pocket 9mm. Not unless you have massive pockets. I looked at the Nano and Sig P290 for pocket duty; they're just not workable as an EDC type gun. Not without dressing around the gun, which is kinda what you are trying to avoid with pocket carry.
