Per the Pazdera book, Legenda jmenem CZ, the CZ 75 SP-01 / CZ 75 SP-01 Tactical started production in 2004 after the marketing department came up with specs for a large capacity, high reliability, exceptional accuracy and robust pistol for police and military special forces in 2002. Prototypes were built in 2003. A few changes were made for production..dropping the ambi-slide stop/release and revising the shape of the rail.
In 2005, they started on a model for sport shooters without the firing pin block (consulted with Angus H, Adam Tyc and other experts in the firearms field) and introduced the CZ 75 SP-01 Shadow in 2006.
The B model of the CZ 75 can be seen as early as 1993. I believe the “transitional” pistols without the firing pin block disappeared after 1995.
