I came across a CZ-75 Retro model in a large gun shop a year or so ago IIRC. It looked so much like the previous Pre-B CZ-75s I'd owned, round trigger guard, spur hammer,etc, that I bought it on the spot. It displayed the usual 100% reliability expected with CZs. It did have a couple features I didn't care for. The trigger has been subtly reshaped, and seemed to give my trigger finger an uncomfortable "slap" with each shot. Something that I'd not experienced with the Pre-B guns. Also, the lower right rear area of the slide has the good sized rectangular hole common to the B series guns with the firing pin safety. The Pre-B guns do not have this hole and it just never looked quite right to me. Anyway, good guns, IMHO, that definitely do look retro........
BTW, I didn't care for the really retro short frame rails either...
