SIG MPX: Video and Details

SIG MPX video

“The next generation of submachine gun is here,” states a SIG Sauer video demonstrating the all new SIG MPX.  The SIG MPX is a new submachine gun that the company is expected to show off at next week’s SHOT Show.

There are a number of features that really set this gun apart from others in this category.  First, according to the video, the SIG MPX is the world’s first submachine gun to work with a fully closed and locked rotating bolt system.  The gun uses the SIG Sauer short stroke gas piston system that the company has used on their other rifles.  There is a last round hold open.
