pocketable 9mm is best

The choice is between a Glock 43, Sig P938 and the Kahr CM9. I chose the latter. A hip pocket kydex rig for normal wear, and a front pants pocket rig for when wearing a backpack. I ground the hell out of the corners, and polished them, both for the sake of comfort and to make it look exactly like a wallet in my pocket. Nobody thinks anything of it when they see that you have your hand in your pocket, and the robber has TOLD you to reach into your pocket, eh? Thus, he EXPECTS to see your hand coming out of your pocket, holding SOMETHING. By the time he can notice what's really in my hand, decide to do something about it, and then reverse his "dont fire unless" message to his hand, I'll have already brained him.

For long drives, I remove it from the pocket rig and stick it in my waistband, under my shirt. If I had a desk job, I'd move it and its rig into my front pants pocket while sitting down. The pocket rig lets you palm the rig and gun from the pants pocket to the coat pocket, when you go out into bad weather,and vice versa when you get in out of such weather. A belt rig, in bad weather, makes you fight your way thru TWO garments, in order to get out your gun, and maybe also handicap yourself with gloves. With your hands in your pockets, you dont need gloves. So that's another bonus. I used to be a cocked and locked SA guy, but i dont trust the Sig brand anymore, their customer service sucks.
