I have both, RAMI and PCR. I'm still trying to figure out which one is more comfortable to carry!
The PCR will probably print slightly more due to the grip (provided that's compared to the 10 rd mags in the RAMI. The extended mags obviously print more).
Of course we all have different physiques and body shapes, so it's different for everyone.
I think what you should be asking is: What holster will carry best and print the least. I believe the holster will be the deciding factor in the decision between the RAMI and PCR.
In my case, the RAMI rides at 4 to 3:30 in a holster with a cant that has one clip on my backside. The cant is such that the RAMI almost sits with its sights on the belt on my side. That cant angle provides for great concealment.
That holster was made for the RAMI. The PCR doesn't fit in it. I have two IWB holsters for the PCR. One is set up almost, but not quite for the same cant and has two clips, one on each side. Because the holster is wider, the clip in the backside is just to the right of my backbone, while the other clips is almost on my right side at 3. (I'm a skinny guy, so there's that). Printing is only slightly more when bending over. Carry comfort is slightly less due to the rear clip being more towards the middle in the back.
The other IWB holster for the PCR is a single clip, for quick taken-on-take-off situations. It makes it thicker but narrower. A bit more comfortable than the dual-clip holster, but slightly larger.
I'm still torn which I like best. Currently, I prefer the RAMI. One thing I want to try is to get the type of holster for the RAMI fitted for the PCR (single clip with cant, again with the guns other side being supported purely by letting the sights ride on the belt). If that works for the PCR as well, that might be my new carry config.
Again, we are all different sizes, and a holstered gun is like a tailored suit. It really all comes down to the holster selection. I think both, the RAMI and PCR, conceal very well, with the proper holster.
