Rock Island Rock Ultra CCO 45 ACP 7 Round Pistol, Black Oxide - 51857

The SP5K was developed by Heckler & Koch as a semiautomatic, civilian sporting pistol that matches the look and feel of the famous MP5K submachine gun.

The SP5K is designed and manufactured to meet the definition of a civilian pistol and marks the return of the roller-delayed blowback system to an HK commercial product. This operating system is legendary in its accuracy and reliability. Originally developed on the Heckler & Koch G3 rifle, it has been used on several HK firearms.

The SP5K retains many of the critical features of the MP5, including its precision machined components and attention-to-detail quality. The SP5K is manufactured completely in Heckler & Koch’s Oberndorf factory in southwest Germany.

The overall length of the SP5K is approximately 14 inches — slightly longer than an MP5K — due to its unique handguard. The SP5K handguard is designed with special ergonomic and safety features to protect the shooter’s hand and provide a comfortable and stable grip.

Despite its size, the SP5K is well suited for sporting use. Using the proven roller-delayed blowback system; the SP5K’s inherent accuracy makes it an excellent choice for target shooting and an ideal home security arm.

And a wide variety of accessories can be added to increase its functionality. A Picatinny rail scope mount is attached to the upper receiver and allows for optional sights to be easily mounted. Covered by Heckler & Koch’s limited lifetime warranty, the HK SP5K is a faithful rendering of the iconic MP5K as a semi-automatic pistol.
