Quite possibly. I carry both, but carry the P-01 more often.
What do you not find comfortable about the P-01?
Many times it can be addressed with the right holster/belt combo, just depends what's causing the discomfort.
I live in Illinois, the law here prohibits carrying in a number of places I normally I frequent, which means I must remove my handgun and store it in my vehicle. So a "hybrid" holster which is more difficult to remove and install is not practical, which leaves me to a the single clip iwb type of holster that is easier to remove and install. The P-01 due to its thickness, weight, and length makes this a difficult proposition to do while sitting my vehicle at least compared to the Kahr CM9 I own. I shoot a shadow in USPSA and would prefer that manual of arms, which I cannot replicate with Kahr due my large hands getting in the way of the it's slide stop. I would like to stay with the CZ platform, which is why I wondered if the RAMI might not be a better fit.
99% of the time I carry a Glock 27 or a 19. The 19 I like to carry in an Aliengear holster for the extra adjustment and comfort. But the 27 I carry in a Bravo Concealment DOS with the belt clips. It's marketed more towards appendix carry, but I've found that it works really well around the 3 o clock area. It's really thin, carries deep, and it slips on and off way easier than the hybrid style. The clips are adjustable, but it's not as adjustable, as comfortable, or as good at concealment as the hybrid style. I have carried the 19 in it plenty of times, but I usually have to either wear a larger shirt or move the holster to a less comfortable position.
You might could try a thin holster like the DOS with a polymer framed gun like the P07, and that'd help with 2 of the 3 stated problems. I don't have any experience with the RAMI but with you saying you have larger hands I'm not sure if that's the best way to go.
