Once you start pocket carry, one won't be enough.
I started with a S&W 642 in a Mika pocket holster. It works pretty good in my jeans, but some of my slacks have the vertical cut pockets, and if someone is looking, they could see the grip. Still, it does disappear really well.
Then I got a Kahr PM9, and another Mika pocket holster. It is shorter than the 642, so I don't worry about the grip showing, but it doesn't seem to disappear as well as the 642. I end up carrying it in a Crossbreed Supertuck most of the time.
Next is a P3AT, and one more Mika pocket holster. This is a pocket gun. I had a problem with the recoil spring hanging out the end of the slide, but KelTec took care of that with no problem. Since then it has been perfect. It conceals very, very well. You can literally forget about it.
I think my last pocket pistol is going to be my Seecamp .32. I'm still waiting on Mr. Mika for the holster. This thing is a jewel. If you appreciate well made guns, this is it. Size wise, you can almost put it on your key chain. It is no target pistol, but neither is the KelTec. In my opinion, they are made for that last desperate effort, or BUGs.
Can you tell I'm happy with Robert Mika's product?
Good Luck.
