A stainless compact would be a nice pistol, and while they're at it, make the mags stainless as well. Will CZ do something like this? God only knows.. I don't see any reason why they could'nt do a compact, either a P01, or a PCR with a stainless slide, barrel, and the controls in stainless, and have a brushed finish on a alloy frame. Making a stainless frame may be a bit harder, as these are cast, compared to a alloy frame that is forged..With a cast frame there is always the possibilty of flaws in the casting, pits, inclusions, are always possible, and with cast steel frames small pits can be covered up with the polycoat, a cast stainless frame dosen't have that luxury, it has to be perfect, any visual imperfections aren't going to do. I suspect this is part of the reason why we don't see as many stainless pistols compared to steel or alloy framed ones..
Any of the pistols on your list would make an excellant birthday gift to yourself, depending on what you're going to do with it..Myself, I'd go with either the P01, 75 compact, or the PCR, if the plan is to use it as a carry gun, For a range toy, the high polish 75b, or the 99041 will do nicely.. The 99041 could be used as a carry gun as well, but, at 44oz with one in the chamber, and a loaded mag, It's not exactly light,,I have a 99021 and that's how I know this , I weighed mine, packed it around for a few days, and came to the conclusion that there are better options..
