Frequently Asked Questions

What are the key features of the Sig Sauer MPX?

The Sig Sauer MPX features a short-stroke push-rod gas system for reliability and recoil mitigation, ambidextrous controls for ease of use by both left and right-handed shooters, and a PDW-style brace for a compact shooting platform. It also comes with integrated flip-up sights.

How does the Sig Sauer MPX compare to the B&T APC9K?

The reviewer found the MPX's ambidextrous magazine release and bolt catch to be more conveniently placed and easier to operate than those on the B&T APC9K. While both were tested for the Army trials, the MPX's control layout was preferred.

What are the potential drawbacks of the Sig Sauer MPX?

Potential drawbacks include its compact size, which might be too small for taller individuals, and a trigger reset that can be tricky during rapid fire, possibly leading to hesitation. The close placement of ambidextrous controls also poses a slight risk of accidental engagement.

Is the Sig Sauer MPX accurate?

Yes, the reviewer found the Sig Sauer MPX to be highly accurate, particularly up to 70 yards, and deadly accurate at 10 yards. This accuracy is attributed to the firearm's design, the 4.5-inch barrel, and the use of a red dot sight like the Romeo 4H.
