Closely resembling the look and feel of the famous MP5K submachine gun, the HK SP5K is a semi-automatic, civilian sporting pistol. The SP5K marks the return of the roller delayed blowback system, which is legendary in its accuracy and reliability.

The SP5K comes with two 30-round magazines and an elastic bungee sling. This bungee sling can be easy installed by snapping it onto the sling swivel hardware located at the rear of the receiver. The purpose of this sling is to assist in comfortable shooting.
