Heckler and Koch (HK USA) | SP5 Magazine | 9mm | Black

HK's factory SP5/MP5 magazine is steel construction in a matte black finish, built to the exact tolerances of the roller‑delayed blowback platform it feeds -⁠- a genuine factory‑spec part, not an aftermarket approximation. A 30‑round standard capacity (with 10‑round compliant options where required) and a steel internal spring back the same reliability the MP5 platform has carried through decades of military and law‑enforcement service. The magazine made to the specifications HK's own Oberndorf factory sets for the gun it's actually feeding.
