I'll end up buying the RM380 just as a way to get practice in with a similar gun without having to shoot my R9. About once every two weeks I shoot 7 rounds from my R9.
When I read the gun forums, no one has anything negative to say about the RM380, but I just don't see it beating out the ultra-cheap LCP which sometimes goes for $199,99 shipped.
I also see a lot of gushing over the Glock 42, which I don't get - but whatever, there definitely are a lot of people who love the Glock 42
