I guess I don't have a deep concealment handgun. I have guns that I carry. They are all basically the same size (the size of a Colt Officer Model 45acp). I typically carry concealed but sometimes OC.
I guess when I am wearing a CrossBreed Super Tuck holster then I am carrying deep concealed.
Kahr PM9. Small, but not micro.
Personally, smallest caliber I feel comfortable with, in the smallest yet reliable model I could find.
Accurate and reliable.
For really deep concealment like swimming trunks that would be my Seecamp .32 stainless.
For T-shirt and blue jeans concealment that would be my Ruger LCP .380.
For casual wear my Kel-Tec PF-9, 9 mm.
For cold weather wear my Star PD .45
and for artic wear my M1A, LOL
I usually carry a Kahr PM9. if not that then a Kel-Tec p3at. I want a Kahr p380. i saw one and it is just as small if not a little smaller then the kel-tec. a seacamp would be a great addition as well. Now if only they made that in 380..ummmm
My Walther PPS 9mm is my baby. I'm really happy with it. It fits in my hand better than Glocks, Kahrs, S&W's. I can carry it on an ankle rig comfortably or IWB and nobody knows I have it. My wife didn't know I was taking it to church for 6months! It works for me.
