Hey gunbuster, from what I've read the frames on the polymer Ramis were prone to deforming (bulging). I'm not exactly sure of the cause, the version is now discontinued. I'm sure if you root around on this forum you'll find some detailed info.
I have a RAMI BD and find it to be the ideal carry size, again with the 10 round magazine. I have a few other sub compacts but they pretty much stay in the safe now.
