Now that is kinda cool. 6" 1911 size, CZ looks with 14 rounds of at least .44 mag energy. Color me interested. What was the Ransom Rest, 25mm for 4 shots at 100 m. That is damn fine workmanship.
103 grains is the heavy bullet. Not so sure. Did not see what bullet diameter, but 7.5 mm is what about .30 caliber? Really not so sure.
It would be fun I am sure, IF production models are available to non mil/leo, and if production models are at the same quality of the test models. Brno is a quality manufacturer, but how many other models from them are available in the US. And proprietary ammo? Unless a major distributor and a major ammo manufacturer gets behind this, it will be a foot note in 5 years and a video on Forgotten Weapons in 10.
All that said, I have no need for one, no use for one, but I still want one. But it would be a low priority.
