I've been a big CZ fan for years, but never got enthused by the RAMI. It feels bigger in the hand than it's size would indicate, and bigger in the holster. I much prefer the Kahrs (PM-9, P9). I have a CM-9 and it's a true pocket gun, but should be used with a good pocket holster.
The RAMI is apparently a fine gun, and once some early "teething" problems (years ago) were resolved, they've been good performers. That said, the CZ P-01 is roughly 3 ozs heavier, only an 1/8" wider, and not quite 3/4" longer -- yet the barrel is more than 3/4" longer. The P-01 holds 14 rounds, while the RAMI holds 9 (in 9mm). Capacity is a factor, and 9 is a big jump over the P9 or PM9 (6 or 7 rounds).
The only person who can answer your question is YOU. You need to handle one and decide if the size trade-off is justified, and how important a couple of extra rounds might be to you. And think about holsters.
