Did the BH guys really fix the sig 320?

Published on December 23, 2025
Duration: 7:17

This video discusses potential modifications by BH Spring Solutions aimed at improving the safety of the SIG Sauer P320 by increasing sear and striker lug overlap. The presenter, Ben Stoeger, believes BH Spring Solutions is directionally correct in their approach to reducing uncommanded discharges, though he notes the lack of definitive proof in BH's own testing methodology. The discussion touches on the importance of sear engagement in firearm design, referencing John Browning's principles.

Quick Summary

BH Spring Solutions proposes modifications for the SIG Sauer P320 to enhance safety by increasing sear and striker lug overlap, aiming to prevent uncommanded discharges. Their approach involves strengthening springs to ensure more secure engagement, addressing concerns about the P320's stock design where overlap is less than 1mm. While the presenter believes their direction is correct, the testing methodology in their videos faces criticism for lacking definitive proof.

Frequently Asked Questions

What is BH Spring Solutions' proposed fix for the SIG Sauer P320?

BH Spring Solutions suggests modifications to the SIG P320 aimed at increasing the sear and striker lug overlap. This involves increasing spring tension to ensure a more secure engagement, thereby reducing the likelihood of uncommanded discharges. They claim their mods make the P320 significantly less likely to fire unexpectedly.

What are the key technical points regarding the SIG P320's safety discussed in the video?

The video highlights that the P320's sear and striker lug overlap is less than 1 mm, falling short of the ideal 1.5 mm or more. It's also noted that the manual safety on the P320 blocks trigger movement but not sear movement, and the sear is held by two springs that BH Spring Solutions deems too soft.

What criticisms are made about BH Spring Solutions' videos on the P320 fix?

Criticisms include the videos being excessively long, containing tangential historical firearm design discussions, and employing testing methods (like dragging guns behind vehicles) that are not considered definitive proof of the modifications' effectiveness. The lack of direct demonstration of a modified P320 failing to discharge under conditions where an unmodified one would is also noted.

Does Ben Stoeger believe BH Spring Solutions' P320 modifications are effective?

Yes, Ben Stoeger believes BH Spring Solutions is 'directionally right' and that their modifications make the P320 'way less likely to go off uncommanded.' However, he qualifies this by stating he cannot definitively prove their effectiveness based solely on the provided videos, but rather on other information he has encountered.
