Light composite frame and hight capacity magazine of 18 cartridges making it a late russian responce to austrian Glock.
The GSh-18 is a rotating-barrel, short recoil, locked-breech pistol with 10 locking lugs spaced equally around the barrel, the large locking surface area resulting in a strong lockup making it suitable for high-velocity ammunition loads.
