Shadow Systems MR918 Combat - 9mm

Availability: In stock (1)

Meet the MR918 Combat.  This is our no-nonsense answer to a fighting pistol but includes features normally found only on the finest custom guns.

The MR918 name comes from the idea of creating a true “multi-role” pistol.  The size and operating system of our online multiple role pistol is inspired by the Glock Gen4 G19 model, but many aspects have been redesigned.

The frame has been in development for 2 years and is 100% a Shadow System design, and not a rebrand of another frame already on the market.  The frame makes use of new manufacturing techniques to wrap more texture around the curves of the frame and put grip in places not normally seen on production guns.
