Caliburn, the base pad on the magazine adds length and is curved like a finger grip. The material is superior to other basepads (will stand up to Gunscrubber). One trick not memtioned in the manual however is the fact that the slide release does not remove by lining up the line on the slide and the receiver as in other CZ's. You line up the dimples on each to field strip the gun. This was a tip from Mike at CZ. I should say that in addition to what has been said, the slide on the 40 P is more nicely finished than my other CZ (true also of the RAMI). It does have a de-cocker, much like the PCR or the 75 BD. I can't answer the question about other .40 magazines, etc. since this is the only .40 CZ I have ever shot other than an IPSC Standard, and its magazines are entirely different.
