TFB FIELD STRIP: The U.S. Army SIG Sauer P320 M17 Pistol


    SIG Sauer M17

    Ah, the famous SIG Sauer P320 M17 pistol, placed into service by the U.S. Army and other branches after a long and pronounced testing and evaluation period that was not without controversy. But, besides a few slight specifications and material treatment variations, the M17 is nearly identical to the civilian P320 pistols laying on the shelves of thousands of local gun shops.

    Kicking off a new Field Strip series here at TFB, the P320 M17 Pistol will mark the start of a pictorial breakdown of every weapon we can get our hands on. Yes, field stripping a pistol such as the SIG Sauer P320 M17 is about as simple as it gets, but as veteran shooters, we sometimes take our knowledge and experience for granted. Somewhere out there a bright-eyed, 21-year-old kid just picked up his first handgun and is wondering how everything fits together. So let’s break it down for him or her. As always, helpful commentary is welcome.

    REMEMBER the four rules of gun safety:

    1. All guns are always loaded.
    2. Never let the muzzle cover anything you are not willing to destroy.
    3. Keep your finger off the trigger until your sights are on the target.
    4. Be sure of your target and what is beyond it.
