ISLAND PORTED GLOCK?! - Derya DY9 Island Honest Gun Review!
This expert review of the Derya DY9 Island, a Turkish-made Glock clone, highlights its attempt to offer premium features like island porting at a $600 MSRP. While praised for its comfortable ergonomics and RMR optic cut, the firearm experienced reliability issues with steel-cased ammunition and a pin walking out during testing. The reviewer notes minimal recoil reduction from the island porting and potential fitment issues with the deep RMR cut.
