I Got My Sig P320 To Go Off... (Re-Creating Viral Incident)

Published on July 31, 2025
Duration: 10:16

This guide details the process used to replicate an uncommanded discharge in a Sig Sauer P320, as demonstrated by an expert firearms instructor. It involves simulating a specific mechanical failure where slide movement, combined with partial trigger depression, can cause the striker to release. The demonstration highlights potential safety concerns related to manufacturing tolerances and sear engagement, contrasting the P320's slide play with that of a Glock 19.

Quick Summary

An expert firearms instructor demonstrated how a Sig P320 can discharge without a full trigger pull by manipulating the slide while the trigger is partially depressed. This phenomenon is linked to manufacturing tolerances, specifically the vertical play between the slide and frame, which allows the sear to be released under specific conditions.

Frequently Asked Questions

How can a Sig P320 potentially discharge without a full trigger pull?

A Sig P320 may discharge without a full trigger pull due to its internal mechanics. If the trigger is partially depressed to the 'wall' and the slide is then manipulated, the sear can be released, allowing the striker to fall and fire the primer.

What is the significance of slide play in the Sig P320 malfunction?

Significant vertical play between the slide and frame on the Sig P320 is a key factor. This looseness allows internal components to shift sufficiently during slide manipulation, even with slight trigger pressure, to release the striker.

How does the Glock 19 compare to the Sig P320 in terms of slide fit?

During testing, the Sig P320 exhibited considerably more vertical play between its slide and frame than the Glock 19. The Glock 19 demonstrated a much tighter and more stable slide fit, suggesting better manufacturing tolerances in that regard.

What safety concerns arise from the P320's potential for uncommanded discharge?

The primary safety concern is the potential for accidental discharge, especially when the firearm is holstered or handled. While holsters offer some trigger protection, the mechanical possibility of the striker releasing under specific conditions is a significant safety consideration.
