To me it's a single action CZ-75B.
Heavy, all steel guns are excellent for the range or home defense, since the extra weight keeps recoil down and makes followup shots easy. No need to worry about light weight, since the pistol won't be carried for long period. Target type triggers are great too, since these increase accuracy on the range.
This one is often shot with 95 gr reloads for low recoil plinking.
