The MR918 name comes from the idea of creating a true “multi-role” pistol. The size and operating system are inspired by the Glock Gen4 G19 model, but many aspects have been completely redesigned. The frame has been in development for two years and is 100% a Shadow System design, not a rebrand of another frame already in the market. The frame makes use of new manufacturing techniques to wrap more texture around the curves of the frame and put grip texture in places not normally seen on production guns.
