The CZ 75 is the flagship model of the CZ handgun line. The CZ-75B features the short recoil, tilt barrel with radial locking lugs. Characteristic features of all versions include: all steel construction, fixed sights, a double column magazine, and slide stays open after last cartridge has been fired. The 'B' designation is an indicator that the model is equipped with a firing pin block safety. The CZ 75 B SA (single action) is identical to the CZ 75 B in all aspects except that it has a single action trigger mechanism and a drop-free magazine.
