Sig Sauer MPX was first introduced in early 2013, though the company is still in the final stages of prototyping. Significant time, effort and tens of thousands of rounds have been fired through prototype weapons, making certain it is completely vetted before it hits the market. Author David Bahde was recently able to test out a prototype MPX in 9mm while attending training at the Sig Sauer Academy, and he offers a full report in the upcoming January 2014 issue of TACTICAL WEAPONS.

Bahde writes, “The MPX is going to be made available in a number of configurations. The standard model has an 8-inch, threaded barrel. The MPX-P is configured as a pistol using the same 8-inch barrel with no stock. The MPX-SD model will utilize a 6.5-inch, ported barrel that is integrally suppressed. For those in need of a shorter version, the MPX-K will use a 4.5-inch barrel. All models will initially be available as select-fire-only weapons, and semi-auto short-barreled rifle (SBR) versions will follow. All are available with either an aluminum or carbon-fiber forend, and a folding or collapsible buttstock. Magazines are built specifically for the MPX by Lancer Systems, and they are available in 10-, 20- and 30-round capacities.”
