Comment:  If you look hard enough you find someone (see quote below from Lou Chiodo)  that agrees with me about the value of the empty chamber as a safe way to carry guns.  It is against the laws of physics as we know it to move a round from the magazine into the chamber without the slide being fully activated first.   If what I am seeing on this is true, this is a gun that is always cocked and cannot be uncocked.  This is highly dangerous!  The striker is always on enough spring tension to fire a round and is depending on multiple safety mechanisms to keep it from doing so.  Yikes!  Personal Opinion:  This explains everything to me as to why there is a design problem going on here.  I want to be able to fully uncock a gun.

The Washington Post explains that what makes the P320 different from others in its class is that it is “effectively fully cocked at rest” and does not draw the striker backward “any meaningful distance”, simply releasing it to detonate the primer.

"SIG Sauer M17/M18/P320 Pistol Just Can’t Seem to Escape Safety Controversies"

June 16, 2025 by Christian D. Orr 

Quote:

An investigation revealed that as of April 2023, more than 100 people had reported that their own P320 fired without anyone pulling the trigger, wounding at least 80 of them, including 33 officers at 18 law enforcement agencies. Ten of these injuries occurred within the agency I myself used to work for as a Special Agent from 2009 to 2011, U. S. Immigration & Customs Enforcement (ICE). (Back then we were issued a different model of SIG handgun, the .40 caliber P229 DAK, which didn’t have these alleged safety maladies.)

My friend Lou Chiodo—former U.S. Marine Corps officer, retired California Highway Patrol (CHP) officer and firearms instructor (he was on duty for the infamous 1992 L.A. Riots), founder & President of Gunfighter Ltd. Combat Shooting Methods Inc. in Chula Vista, California, and author of the excellent books Dynamic Training Concepts and Winning a High-Speed, Close-Distance Gunfight—adds:

“I thought was worth noting is Sig responded that in their literature provided with the handgun it advised not to carry with a round in the chamber. Just my opinion, if that’s the level of confidence they have in their 320, why should I trust it? This is a duty pistol. We carry rounds in the chamber. If they don’t think it can be trusted with a round chambered then table it off the market. Wow.”
