imo
I have two kahrs that are my concealed carry pistols....I gave a link below my thoughts for each gun.
PM45.............As far as concealed carry goes............probably none better for comfort and none smaller. Please note the dimensions and size and compare to other guns. It is a handful because of the short barrel. But if you take the time to shoot and break it in
......man, it is a great CCW for .45.

My other main squeeze is kahr MK40 all stainless. I carry this more than all of my other guns put together. The best shooting small handgun I've ever owned. LCP/s keltecs CZs I've shot and owned alot em, but none IMO compare to this MK40. Granted this gun is heavier and bigger, but still very small compared to say a glock 26. (Yuck I dont even like saying that G-word) I just like having that .45!!!! Wish Kahr made an MK45 ............mmmmmmmmmm aaaah aaaah aaaaaaaaaaaaahhhh

Obviously my favorite gun is an H&K full size USP. (.45) but it is just to bulky for ccw. And with that said I give you my top 2 rules for purchasing a CCW gun......and most here will probably agree.
This gun is on your side for one thing protect your life so first and foremost...
**********RULE #1 Hit at least 8 out of 10 rounds from 25 yards on a 1ft by 1ft target.
(In other words, how well do you shoot this gun?)
**********RULE #2 How well can I conceal this pistol.
(This comes down to many aspects of CCW. How your dress. Is the gun you shoot popular enough to get accessories that are comfortable. This is very important " COMFORTABLE" !!!!!!!!!!!! You can't underestimate that because what good is that gun if you leave it in your truck or at home because it isnt "COMFORTABLE". Does the gun dissappear when holstered. There are tons of things that you will learn over time by experience that no one here can tell or teach you about simply because of your taste and comfort levels.
One last thing before I go...You don't need a big caliber gun to protect yourself. It's proven!!!! Size will not compensate for poor shooting. Many special forces still carry .9mm throught out our military. If you can't hit the target,...............find a different gun you can hit it even if its a .22. If it means your life I'd rather hit them than scare em!!!!!!!!!!!!
