Problem is, bigger guns typically get left home. I've carried every style, every which way and end up not bringing it along all the time. At least a pocket gun is always with me.
Check out the XDs.....I am telling you that is a badass concealed gun.....kicks like a 9mm
Try it out
It's an amazingly compact .45 ACP, and reports are mostly positive as to its shootability and reliability. If you need the smallest .45 ACP available, that's a great pick. Personally, I'd rather have twelve rounds of 9mm than five rounds of .45 ACP in a similar sized package. Yeah, the S&W M&P 9c is a fraction of an inch thicker than the XDs, but since it conceals well, and carries comfortably, in a Milt Sparks VM II, I see no need for a reduction by a fraction of an inch in thickness, and no way I'd carry either of them as a pocket gun. For me, an "always carry" pocket gun means a "mouse gun," i.e., something like a North American Arms Mini-Revolver or a Seecamp-sized auto pistol.
