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. For more comfortable shooting, the SP5L is equipped with an elastic bungie sling. The sling is easily installed by snapping it onto the sling swivel hardware located on the rear of the receiver.
