P320 Goes OFF in Holster UNCOMMANDED | I don’t think so

Duration: 2:32

This video provides a detailed mechanical explanation of why the Sig Sauer P320 is unlikely to discharge uncommanded, particularly when appendix carried. The instructor highlights the crucial role of the trigger mechanism in disengaging the firing pin block. An upgraded Agency Arms trigger with a blade safety is also discussed as an additional layer of security.

Quick Summary

The Sig Sauer P320's internal mechanics prevent uncommanded discharges because its firing pin is blocked by a safety lever. This lever must be depressed by pulling the trigger for the firing pin to move forward and strike the primer, ensuring a high level of safety during carry.

Frequently Asked Questions

Can a Sig Sauer P320 fire without the trigger being pulled?

No, the Sig Sauer P320 is designed with a firing pin block that prevents the firing pin from moving forward unless the trigger is intentionally pulled. A small lever within the trigger mechanism must be depressed to disengage this block, making uncommanded discharges highly unlikely.

What is the role of the trigger in preventing accidental P320 discharges?

The trigger is the sole mechanism that disengages the firing pin block in a Sig Sauer P320. Without the trigger being pulled, the firing pin is physically blocked from moving forward, thus preventing the firearm from discharging.

Does an aftermarket trigger like the Agency Arms blade safety improve P320 safety?

Yes, an aftermarket trigger like the Agency Arms blade safety trigger can provide additional peace of mind. It adds an extra step of intentional depression of the blade safety before the internal firing pin block can be disengaged, further reducing the risk of accidental firing.

Is appendix carrying a Sig Sauer P320 considered safe?

Based on the mechanical design, appendix carrying a Sig Sauer P320 is considered safe. The firearm's internal safety mechanisms, specifically the firing pin block, require deliberate trigger manipulation to function, making accidental discharge highly improbable during normal carry.
