Home Defense with the Heckler & Koch SP5K

The MP5K 9mm machine gun is renowned for its reliability, compactness, and light weight. HK calls it “the ultimate Close-Quarter weapon”. Well, it’s one of the top close-quarters weapons. And now there is a civilian legal version the SP5K pistol. It’s semi-automatic, and lacks a stock, so it is not an NFA item. HK also replaced the vertical forward grip in the MP5K with a textured horizontal grip, to make it civilian legal. (However, it is not 50-State legal, so check your local laws.)

Here’s the HK webpage for the USA site. HK says: “The new SP5K was developed by Heckler & Koch as a semiautomatic, civilian sporting pistol (hence the “SP” prefix) 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.”

Yes, the SP5K is pricey. But as a reliable, compact, light 9mm platform, it’s an excellent choice for home defense. It’s sling can be used to help steady the pistol, making it more accurate despite the lack of a stock. And at 4.2 lbs, it’s lighter than any 9mm carbine and heavy enough for low recoil.

Here’s an good article on the gun at The Firearm Blog.

One Response to Home Defense with the Heckler & Koch SP5K

  1. The correct term for both firearms in your otherwise excellent article is a “sub-machine gun” and, only IF the firearms listed are fully automatic Class 3 firearms. Otherwise, these are merely semi-automatic firearms, (one round fired per ONE pull of the trigger).
    Machine guns ONLY refer to rifle caliber cartridges fired in fully automatic belt or box fed , sometimes crew served machine guns.
    The difference IS very real, and mistakes play into the hands of those despots already seeking to deprive us all of our Constitutional Rights we have here in the U.S.A……so far, at least until November.
