This video details a critical incident during a firearms class where a custom-built pistol, featuring numerous aftermarket parts, experienced unintended discharges. The instructors meticulously troubleshoot the issue, identifying tolerance stacking and specific magazine fit as the likely culprits. They emphasize the importance of testing aftermarket components and the potential pitfalls of combining non-OEM parts.

This video discusses the controversy surrounding the Sig Sauer P320, specifically addressing claims of out-of-battery detonations. It highlights a shift in the Sig Armorer's public stance, moving from developing a fix to stating the current manufactured guns are safe, attributing issues primarily to holsters and training. The discussion also touches on potential manufacturing defects like mixed-up takedown levers and tolerance stacking, suggesting that while extreme configurations might be rare, other less obvious unsafe configurations could exist.

This video features LFD Research detailing their investigation into uncommanded discharges of the SIG P320. They demonstrate how specific part combinations, tolerance stacking, and manufacturing variations can lead to the firearm firing without a trigger pull. The discussion highlights potential design flaws and the importance of understanding firearm mechanics for safety and reliability.

This video provides a nuanced analysis of the SIG P320's unintended discharge issues, revisiting earlier findings with updated information. It delves into the mechanical differences between the P320 and Glock, particularly concerning striker design and trigger pull. The discussion highlights potential causes like drop safety flaws, lack of external safeties, tolerance stacking, and quality control lapses, while also debunking manufacturing cost rumors. The expert assessment emphasizes a deep understanding of firearm mechanics and historical safety concerns.

This video delves into the ongoing discussions and criticisms surrounding the SIG P320 platform, particularly focusing on issues of uncommanded discharges and potential manufacturing defects. The speaker, Ben Stoeger, reviews comments from his audience, highlighting concerns about tolerance stacking, MIM processing, and quality control. He discusses his own modified P320 Legion X5, noting that while he now enjoys shooting it after specific upgrades, the underlying issues raised by the community and documented incidents remain significant.

This video demonstrates a compatibility issue between a Sons of Liberty Gunworks (SOLGW) lower receiver and a Forward Controls (FCD) magazine catch, specifically when using polymer magazines. The instructor highlights that this is a case of tolerance stacking, where two otherwise functional parts do not work together in a specific combination. The solution presented is to replace the FCD magazine catch with a standard one.

Dustin Sanchez, a seasoned competitive shooter and media professional, discusses the critical role of tolerance stacking in AR-15 performance, emphasizing the JP Enterprises bolt as a key upgrade for reliability. He also provides practical advice for new shooters looking to enter competition, stressing the importance of community support and starting with essential gear rather than expensive upgrades.
