I have a CZ Rami 9mm in the alloy frame. It's got 950 rds through it so far and has been a fun gun to shoot. It jammed on me 3 times in the first 100 rds with reloads so I stick with WWB and Remingtons now. It has yet to jam on me with factory ammo. My only complaint with the gun are the sights. I wish they were real night sites instead of the glow in the dark paint. Also you will need the XD Pearce extension if you're going to use the 10 rd mags. I tried to shoot with my pinky hanging off the gun and it never felt comfortable to me. The extension makes this gun a pleasure to shoot. I prefer the alloy frame over the polymer, it just feels better to me. I also like the fact that you can change the grips.
I wouldn't get the Rami in .40SW. There are too many people having problems with theirs for me to gamble my money on one.
