It is basically a 75 on steroids. They took the basic CZ75 design and enlarged it slightly to accommodate the larger 45 round and magazine. The controls are the same including the location and method of function of the frame mounted safety. It uses a locked breech, linkless tilting barrel design borrowed from the Browning it resembles.
Pluses...
It is a 45, uses a 10 round magazine, can be carried condition 1 or with hammer down for a DA/SA action. Very good ergonomics.
minuses...
It is larger than the 75, to carry DA you have to carefully lower the hammer on a live round, grip is rather fat but thinner grips are available, it is not a light handgun.
The 97B shots very well just like it smaller kin but maybe uncomfortably large for some. Holsters may be harder to find for it than for the 75 as the 75 will work in just about an Browning HP or 1911 holster...the 97B may be too tight in them.
