Kahr firearms and .380 pistols
I remember the first time I ever shot a .380 pistol and it was an NAA Guardian gun. They seemed so small that my initial impression was it was just a step up from a fly swatter. I’ve done some not so scientific ballistics tests on metal fence posts and saw the penetration differences between a .38 Special and a 9mm, and there is a substantial difference between those calibers and penetration. The .380 is practically a 38 Special short and people need to be realistic when they want to consider what a firearm engagement will be with a pocket pistol such as this. Worrying about accuracy ans sights on this gun IMHO is pointless because this is the type of firearm that will only stop a threat if it’s put into the main reactor of the Death Star or you unload the whole thing and hope the bad guy isn’t wearing body armor.
I have shot a lot of Kahr firearms and I think the 9mm pistols are very well made and I see no reason to change the caliber to a smaller one when the 9mm already fit in your pocket. Kahr magazines are what you want to use in the gun and I would not compromise on this issue with a concealed carry firearm. There is nothing wrong with having range magazines so you don’t wear out your primaries, but it’s mostly only with 1911 firearms would I stray from factory magazines. If you have a semi-auto that holds 5-7rds and can carry a backup magazine, and you’ve done some training, you should be good to go.
