Being as this old thread has been recently revived;
The CZ 75 Original, RSR Special
(aka 'Retro') was made for RSR distributors circa 2004.
Based on information presented on the internet, less than 1000 were made.
This one was purchased in 2004.
At the time I was looking for a full size frame for my Kadet kit (initially was on a 75C).
This was the least expensive, new, full sized 75 I had been able to find ($359).
The grips it came with sucked and they were replaced with these (much preferred IMO) repro waffle grips.
Hogue grip screws replaced the originals.Edited to add: Mec-Gar, as well as CZ 25 round mags work just fine in this one.
