The Genesis of the Sig Sauer MPX
As the “World’s Oldest and Largest Firearm Authority,” American Rifleman is often the first draft of firearm history. Back in 2013, as part of a visit to the SIG Sauer factory in New Hampshire, American Rifleman's Brian Sheetz got an exclusive look at the SIG MPX submachine gun—while it was still in development. This was the first detailed explanation of the selective-fire gun aired anywhere. More than two years later, the MPX has changed and evolved, and you can see the latest information on the MPX here. But this snapshot in time shows how the MPX as system has followed a slightly different developmental track since our original American Rifleman TV coverage aired. For the latest on the MPX family of firearms, check the latest from SIG Sauer
