Completely ambidextrous, the SIG MPX is great for left- or right-handed shooters with its dual-sided selector switch, magazine release, charging handle and bolt release.

A short-stroke gas piston allows the SIG MPX to run all weights and brands of 9mm ammunition with no adjustments to the gas valve.

Customer Comments & Questions

Customer Reviews

(5 out of 5) Perfect PDW with just a few upgrades.
by from Sandston, VA on

I bought this strictly for in-home defense. Top 3 requirements were weight, maneuverability, and reliability. Let me start by saying I am over-the-moon happy with this firearm. With nearly zero recoil and zero malfunctions, this weapon fires on command and is laser accurate.

 The only downsides, as I see them, are the near requirement to upgrade the charging handle to the Next Level Arms Ambi charging handle for the MPX and the need to swap out the grip. In this case I chose the Mission First Tactical Engage v2. Now after those two easy steps... I believe I am trusting my life and my families with one of the finest pistol caliber weapons on earth.

 As far as attachments, I highly recommend the Cloud Defensive Optimized Weapon Light OWL and the HOLOSUN HS510C. Lastly, perfect fitting hard case is the Condition 1 18 Medium Waterproof Protective Hard Case with Foam. God bless and stay vigilant.
