E&C EC-1101 aka G17 is a budget copy of the VFC G17 models. It lacks the markings on the slide - it comes clear of any, but the rest is good copy of the whole VFC system. The upper slide is metal, the lower is made out of polymer. The recoil is good and snappy. In general, the build quality for the price is very good, but as it is low-budget replica with metal slide, it does not come with warranty.
