If you look at my picture above the DB9 is right above the CM9 and it is a noticeably smaller pistol (Both 9mm parabellum). The CM9 is a nicer gun than the DB9 in pretty much every conceivable way... BUT I can pocket carry my DB9 and the CM9 is too big. Of all my guns the DB9 is the most unpleasant when it comes to recoil BUT it is a carry gun! A few magazines through it at the range is all I ever want to shoot it... but I know it will be ready to go should I ever need it. I have never had a single misfeed with my DB9! My CM9, LCP, and P32 are the same in having never has a misfeed.
I used to carry my P32 every day at work where printing wasn't an option. I work from home now, so I shove the LCP or DB9 (depending on my pants) in my front pocket when I leave the house for an errand.
If someone could shave a bit off the dimensions of the DB9 by chambering a similar gun in 30SC I would definitely buy one (if it were reliable)!
I Love the whole idea of the micro double stacks BUT for me if I am going to carry a bigger gun I will go up in caliber rather than up in round capacity. I.e. If I want to IWB carry I will carry my XDs .45 rather than a double stack micro nine. Just my personal belief that the first round is the one that counts when it comes to self protection.
