I have the Sig p239 in 9mm and can give some input on that pistol. I have no experience with the Rami. When I want to carry a single-stack 9mm the 239 is a pretty good choice- light, reliable and accurate. I have a couple thousand rounds through mine without any problems (mostly 124 grain Remington Golden Sabre JHPs). If I carry a double stack 9mm I prefer the CZ 75 compact (no rail). You can't go wrong with the Sig p239. I hope someone with Rami experience will also comment on that pistol.
