HK SP5 9mm Luger 16.57in Matte Black Modern Sporting Pistol - 10+1 Rounds - The Heckler & Koch MP5 is arguably the most imitated pistol-caliber carbine in the world. But even a pretty good copy is still just a copy. The truth is, you can only get a real HK from HK. And now there is finally an authentic sporting version of the MP5 in the US, and it's a real HK. The New SP5 will make all those generic MP5 copies out there look like nothing more than gun store consolation prizes.The SP5 was developed by Heckler & Koch as a semiautomatic, civilian sporting pistol that matches the look and feel of the legendary MP5 submachine gun.
