The interface by which accessories attach to the Heckler & Koch MK23 SOCOM pistol employs a specific standardized measurement system. This system allows for the secure mounting of suppressors and other tactical equipment. It is not a typical or universally common size found on other firearms.
This specialized mounting system ensures compatibility with a limited range of purpose-built accessories designed to withstand the high pressures and operational demands of the weapon. Its adoption reflects the MK23’s design as a specialized offensive handgun for military and law enforcement applications, prioritizing durability and performance under extreme conditions. Early designs often lacked standardization, but the MK23 moved towards a more defined, if unique, specification.
