I've owned a Ranger, AL Interarms .380ACP PPK for a few decades. It's always been accurate and reliable for me but I won't recommend it for others without giving them the entire rundown on the gun.
1. Chambering it from a full magazine was quite difficult. The design of the stripper rail tended to hang up on the cartridge rims. This wasn't a problem when firing, but getting that first round chambered manually could be a real problem. After owning it for many years, I finally analyzed the issue and did a mod on the gun that mostly took care of this problem.
2. The sights are off significantly and although the rear sight is drift adjustable, the amount of drift that would be required to get it on for windage would be unacceptable in a compact gun. It's also off for elevation and altering the front sight to deal with that isn't really feasible since it's actually part of the slide.
3. I've carried it in a belly band a lot and had to spend a good deal of time rounding off sharp edges. It's a stainless gun, so there was no need for a refinish, and the results were actually pretty subtle, but given that it was obviously meant to be concealed, one would think a detail like that would have been handled by the maker.
4. Finding magazines for the gun that don't have a finger rest is just about impossible.
All of that said, I like the gun and would buy another one if I could find one.
