I have a 75B Compact and a P01. I?ve looked at the PCR plenty of times and almost plunked cash down a few. For me, since I carry OWB, the rail on the P01 makes little difference in how it carries, so I?ve never seen much personal value in the lack of a rail. The PCR sights and LCI have always put me off a bit as well too.
The 75B compact is very nice but does come with a bit more weight. Given a proper belt and holster, that weight is almost insignificant. The weight does improve the feel when shooting it though, but not that much. The aluminum frames on the P01 and PCR deaden the felt recoil a bit similar to the effect of a poly gun but without the flex.
If you don?t carry IWB, the PCR seems to bring little to the table for the cost of fewer rear sight options and an overly long slide stop pin. I?ll probably end up with one some day but for now, my P01 fills that role quite nicely and can do nightstand duty with a light if I?m traveling and don?t have the dedicated nightstand gun with me.
