My experience relates only to the .380 (CB380 maybe?) and the .22lr derringer, so they may not be relevant to the patriot.
I never could get the .380 to be reliable. I had them work on it twice, and in the end it was an ok range toy (provided you used fmj ammo) with the occasional malfunction.
The derringer was too big and heavy for what you got from it. It was very unnatural to operate the safety. Slow to use, HORRIBLY inaccurate (yes, I know it has an insanely short barrel, but I found it completely unacceptable). I killed a chicken with it in my shed using subsonic ammo with VERY little recoil. It took me 4 shots to hit the bird which was holding extremely still hanging upside down from me about 2 feet away. I'm not a competition precision shooter, but I'm not a slouch either. It is the only gun I've ever shot that I can say without a doubt that the gun was less accurate than the shooter.
That being said, my experience with the company itself has been wonderful.
But for around the same price as an LCP, a Keltec PF9, and only $60 less than I paid for my used Kahr CW9 which has performed flawlessly. I don't know that I would personally take the risk.
