FWIW, I absolutely love my RM380. So much so that I had it hard-chromed (the Remington finish from the factory is awful). I upgraded mine with the Galloway spring kit, and the trigger is very nice now. I should also point out that it has fed and fired EVERY type of round I have attempted, no small feat for today's micro market.
It was that love of the RM380 at lead me to the Rohrbaugh, and all I can say is that the R9 is better in EVERY way than the Remington (save that it is a touch ammo-picky, but that is a small price to pay to shoot 9mm out of this little package).
