Heckler & Koch SP5L 16.57" BARREL 9MM The SP5L was developed by Heckler & Koch as a semiautomatic, civilian sporting pistol that matches the look and feel of the legendary MP5 submachine gun. Designed and manufactured to meet the definition of a civilian pistol, the SP5L is loaded with authentic features, like a 16.5” Navy barrel with threaded tri-lug adaptor, paddle magazine release and fluted chamber. The backbone of the SP5L is the roller-delayed blowback operating system, which is legendary for its accuracy, reliability, and smooth shooting dynamic. Originally perfected on the Heckler & Koch G3 rifle, it has been used on several other HK firearms still serving today around the world. The SP5L is manufactured in Heckler & Koch’s Oberndorf factory in southwest Germany. It retains many of the critical elements of the MP5, including its precision-machined components and attention to detail. This high level of quality and workmanship is a result of making the SP5L in the same factory, on the same lines, and by the same workforce that has been making MP5s for years.
