I have the Rami P in 9mm and my father inlaw has the Rami alloy in .40sw. I would suggest the metal frame in the 9mm (short barrel pretty light weight gun the .40 is really snappy). I would also suggest the 9mm due to reliability, there has been quite a few problems with ftf's in the .40. I've only put 150 rounds through my gun and have never experienced a ftf. The accuracy was amazing for a 3" barrel right out of the box and the more i shoot it the better it feels. I think I like the alloy frame more due to the rubber grip and the fact that it doesn't weigh any more then the poly. I bought mine at a gun show for what i feel was a pretty good deal or i would have gotten the alloy.
