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.
