Gun Tests magazine did a comparison of the P3AT and LCP. They gave a slight edge to the P3AT mainly due to more positive checkering on the grip and the LCP had some bad FTF. There was a problem with the P3AT trigger but it functioned without a problem. They also said that the major components were not interchangeable. "We liked the concept of these small 380s very much, though we thought both guns needed some attention before we’d consider them ready for the street. The Kel-Tec definitely needed some file work on its trigger nose. The Ruger needed internal deburring and a touch of polishing. Both guns would benefit from sights twice as high as they now are, though that’s not necessary. Everyone who handled the two guns preferred the coarser checkering of the Kel-Tec, though the Ruger’s looked nicer. If there’s a better 380 concealment handgun than the P3AT, we would like to know what it is. These guns are both great, but I narrowly preferred the Kel-Tec."
