Read Gun Tests Rating and Recommendation

We liked the SIG P320-M17's reliability and features. The grip fits most hands well and the sights are excellent. We did not like the trigger as well as the other DAO handguns. It was too heavy for our tastes. The pistol is a good choice for those who prefer modular construction and adjustability.

The SIG P320-M17 differs significantly from the P320. The P320-M17 comes standard with SIGlite front sights and an optic-ready removable night-sight rear plate. The slide is coated in the same coyote tan PVD as the military version, and it includes the same coyote tan grip module.
The SIG features an ambidextrous safety (right arrow) and slide lock (left arrow). The ambi safety and slide lock are ergonomic and well designed. SIG's trapezoidal-shaped magazine release (bottom arrow) works well in speed drills.
An important consideration for military use is that the pistol be ambidextrous.
The SIG's rear sight plate can be removed for mounting a red dot. Note the squared-off rear face that may be used to rack the slide under duress.
It took some time to get the feel of the SIG P320-M17, We had the occasional flyer.
