Military Heritage of the M11-A1

To understand the M11-A1, we have to appreciate its origins. The M11 designation was given to the SIG SAUER P228 when it was adopted by the U.S. Armed Forces. It became standard issue for military criminal investigation divisions, select special operations units, and Air Force pilots. The M11 was prized for being compact yet highly accurate, making it easy to carry while still delivering excellent firepower.

The M11-A1 is the civilian and law enforcement evolution of this legendary platform. While it retains the original P228 dimensions, SIG SAUER has enhanced it with modern upgrades:

• Enhanced corrosion resistance thanks to a Nitron-coated stainless steel slide.

• Internal coatings for extended service life in harsh environments.

• SIGLITE night sights for superior low-light targeting.

• Short Reset Trigger (SRT) system for faster follow-up shots.

This pistol is as close as civilians can get to owning the military’s M11, while benefitting from enhancements that make it even more versatile.
