It seems obvious that the pocket holsters would be interchangeable between the LCP and P3AT. Any chance the mags would be too?
Ruger made a comment about their source for the LCP mags that would be easy to interpret as meaning that they used the same mag manufacturer that sources the Kel-Tec P-3AT magazines. Given that the LCP seems to be a complete copy of the P-3AT, I wouldn't be at all surprised if the magazines were interchangeable. Ruger didn't do any engineering, so the mag supplier wouldn't need to either.
I'm still surprised that so many people don't care if Ruger ripped off Kel-Tec. If they can buy a Ruger at a good price, they seem happy to do so. I suspect many of these are the same people who publicly berate Kel-Tec and give them no credit at all for all the development they did on the P-3AT, and will now sing the praises of the Ruger, even though it's the same design and they ripped it off Kel-Tec. Everything that Kel-Tec does is wrong, by definition, and everything Ruger does is right, by definition. :banghead:
This is a whole new type of product for Ruger, and they may be in for an education. These tiny and powerful pistols are twitchy and the manufacturing margins are much slimmer. Adding a few ounces to the slide will help improve their operating margins although most people want a tiny pocket pistol as light as possible and the LCP is about 30% heavier than the P-3AT. That'll help reduce limp wristing, but the part tolerances are tight too, and it may be a challenge to Ruger to make money on their Lame Cloned P-3AT.
If I was in the market for a pocket .380, I'd wait a few weeks for the Kahr .380 that's coming, and not just because of Ruger's complete lack of ethics. The Kahr sounds like a great little pistol, and unlike Ruger, Kahr DOES have a lot of experience making pocket pistols. I love my Kahr PM9. You can bet Kahr does have engineers capable of designing a good pocket .380, and company leadership with more pride and ethics than to blatantly rip off a competing company.
No matter how you cut it, whether Ruger doesn't have the engineering talent to make a better pocket .380, or their management either doesn't have confidence in their engineers or is unethical enough to rip off Kel-Tec, either way it doesn't say anything good about Ruger and Ruger's future. The best they can do is copy Kel-Tec, and meanwhile Kel-Tec is off innovating and creating really neat new products like the RFB (innovative and very high quality .308 bullpup), the SU-22, the PLR-22, etc. The new versions of their SU-16 are going to cut into the AR market some more.
