Isn't it essentially a Turkish made Tanfoglio?
Nope! The Sarsilmaz/SAR USA Pistols ARE mostly Turkish made Tanfoglio Pistols, from a design point of view.
Tanfoglio and Sarsilmaz were business partners at one time, hence the Technology Transfer.
Note that the Sarsilmaz Pistols use the superior Martin Tuma designed Automatic Firing Pin Lock that Tanfoglio Pistols use.
Also, there is no front Barrel Bushing on the Sarsilmaz Pistols like the Tanfoglio Pistols.
The TriStar/Canik series of Pistols are more of a clone of the actual Cz75 design.
The TriStar/Canik Pistols use the same Automatic Firing Pin Lock design that Cz uses. Note the Roll Pin in the Slide near the Rear Grasping Grooves.
Most, if not all, TriStar/Canik Pistols have a front Slide Barrrel Bushing.
My TriStar/Canik T-120, for example.
