The first thing to notice is just how thick the gun is. It feels fatter than G17, on par with USP. I liked the ergonomics overall. Although it is difficult for me to put it on safe with the one hand, it is easier for me to take that safety off than on CZ-75 (I'm so used to 1911 that it's difficult for me to make an unbiased assessment). For some reason, there's no decocker. But then you aren't going to carry this thing concealed anyway, so whatever. I don't have any beef with the unusual dual-feed magazines, I think they work fine. The K Concern demoed a version of Grach at the Armia-2018 expo, which has 3 feed lanes, and central-feed magazines. The new gun can feed from both types of magazines. Not sure what that was about. On the U.S. civilian market, I don't think this thing would be competitive with SIG P226 and HK USP, unless priced way lower, kind of like REX Zero. But we also have bargain priced Taurus PT92 and other such guns. The gun is fine, but it's not in any way "better" than SIG and HK. Note that it's unclear if Viking is +P+ rated. Grach is, but this is different. Buying either Grach or Viking for cops and military also sounds improbable. I'd take P320 over this any way, simply because I have to carry it a lot and shoot it a little. We don't have any of that super-powerful 9mm ammo in inventory. P.S. Mags are not free-drop. Not sure if it's the design or the specific unit.
