I recently picked up a used Kahr P380 at my local gun shop. I had ended up with a credit after selling a hunting rifle and decided to give it a try. Have heard great things about them, quality components, match barrel, and excellent useable sights.
Went to Reed’s Indoor Shooting Range in San Jose. My favorite indoor range. I bought some cheap hardball ammo for some initial testing and then three boxes of self-defense ammo for accuracy and function testing. I shot ten rounds of each of the self-defense ammo at a close range of 21 ft or 7 yards.
- ARX Inceptor 56 gr / 1260 fps / 197 ft lbs
- Hornady Critical Defense 90 gr / 1000 fps / 200 ft lbs
- Remington Ultimate Defense 102 gr / 815 fps / 150 ft lbs
ARX INCEPTOR
I started off with the ARX Inceptor which is a new type of bullet. They are a solid injection molded of blended polymer-copper not intended for expansion but rather provide displacement based on the fluting and high velocity. The ARX started off quite well with my first three shots in the X ring. There were no malfunctions. Recoil was quite manageable. Result: 3-9s and 7-10s with 4-x.
Hornady Critical Defense
The Remington Ultimate Defense rounds were a little harder to control than the ARX. They also functioned flawlessly. I seemed to shoot left with them, not sure if it’s me Accuracy was 3-9s and 7-10s with only 1-x. I would feel comfortable using this for self-defense.
Remington Ultimate Defense
The Remington Ultimate Defense was the only brand that had any malfunctions with a single stove pipe. The accuracy was also a little worse than the Hornady with a final result of 1-8, 2-9, 7-10 with 1-x.
I enjoy shooting the little P380, it is surprisingly easy to shoot and pretty accurate. I think I would go with the ARX load. It offers controllable shooting and some impressive results if you watch the tests on their web site.
