I can attest that the Umarex/Walther/Colt shoots wonderfully. Shot a hundred rounds through a new one last weekend with a bunch of cheap ammo without a single issue. The feel was spot on with a Springfield Armory 1911 in .45 and was why my friend had purchased it in the first place. It seems the only one really available currently is the rail version, as I was/am looking for one myself. I know another guy who had the new Browning on order but after shooting Umarex he canceled his order (it is a slightly scaled down size). I have seen them locally for 375ish.
Ruger SR-22, Browning Buckmark Camper URX, Sig P250 2Sum 9mm, Beretta Nano, Winchester 101 Trap, CZ 512 Mossberg 500 Flex, Carbine MForgery, and soon a rifle length MForgery........and counting. Damn this is fun
