First seen in 2020, Heckler & Koch's SP5 pistol is worth a closer look again in 2021, simply because it's as close as American consumers can get to the genuine article that is the MP5 submachine gun, at least without spending a significant amount of money on an NFA-registered example. The H&K SP5 is a semi-automatic, large-format pistol that's built on the same assembly line in the same factory as the real MP5 in Oberndorf, Germany.
This Heckler & Koch SP5 pistol is based largely on the Navy version of the MP5 submachine gun. This version includes the threaded tri-lug adapter at the muzzle, a paddle-style magazine release paired with the push-button release, and an ambidextrous selector switch. Otherwise, this SP5 includes many of the same features and controls as its select-fire cousin.
Since this is sold commercially as a semi-auto-only, non-NFA, large-format pistol, the Heckler & Koch SP5 does not include a stock or stabilizing brace with the gun. Instead, a polymer cap at the receiver is topped by a mounted sling swivel, which pairs with the elastic retention strap that ships with the gun. When wearing the elastic strap, shooters can stabilize the platform by driving the pistol out in front of their chest, which puts tension on the strap and helps to minimize recoil and muzzle rise.
