Videos tagged with Sear Engagement

This video details a malfunction in a custom-built PSA Dagger firearm, where it exhibits unexpected full-auto-like firing behavior. The speaker, demonstrating experienced knowledge of firearm components and pricing, compares it to a standard Glock and discusses potential causes related to trigger reset or sear engagement. The guide outlines steps to diagnose such issues, emphasizing the importance of understanding build components and potential repair decisions.

This video, presented by David Rickert with high expertise in firearms safety, identifies 13 handguns with significant safety flaws, including drop-fire hazards and potential for unintentional discharge. It details specific models from Ruger, Smith & Wesson, Taurus, Walther, and Sig Sauer, referencing safety bulletins, recalls, and legal settlements to inform consumers about critical risks.

This guide details how to inspect a used pistol before purchase, drawing on expert gunsmithing knowledge. It covers identifying wear from high round counts and carrying, checking for poor modifications, and assessing structural damage. Key inspection points include the breech face, forcing cone, barrel interior, and frame integrity. Functional tests for safeties, trigger reset, and sear engagement are crucial. Following these steps, as demonstrated by an expert, helps buyers avoid problematic firearms.

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.

This video provides an in-depth mechanical breakdown of the Pieper Revolving Carbine, focusing on its unique gas-operated system and stretched-out rifle configuration. It details the single and double-action lockwork, explaining how the hammer, trigger, and various arms interact to cycle the action, lock the cylinder, and ensure proper sealing. The explanation highlights the system's complexity compared to simpler designs while illustrating its functional mechanics.

This video discusses the practical implications of carrying a Beretta M9A4 in a half-cocked position. The speaker argues that aggressive drop tests often result in the hammer naturally falling to half-cock, suggesting that carrying it this way is generally safe and does not significantly increase the risk of damage. Furthermore, it is noted that carrying in half-cock makes the double-action trigger pull considerably easier.

This video discusses Sig Sauer's shift in tone regarding P320 issues, highlighted by a new instructional video on inspecting the firearm. It covers the disallowance of the P320 in some USPSA matches and explores potential causes for malfunctions, including component wear and assembly errors. The discussion also touches on the Air Force's inspection criteria and the ongoing debate about the P320's reliability.

This video discusses a concerning firearm malfunction where a 'Franken gun' discharged when the magazine was struck. It delves into the controversy surrounding the Trigger Tech ACE trigger, with insights from Johnny Glock and Trigger Tech regarding its performance in drop and impact tests. The speaker also expresses positive anticipation for future collaborations with Kimber.

Questo video tecnico analizza la meccanica della SIG Sauer P320, esplorando le ragioni dietro i recenti incidenti e le restrizioni d'uso. Vengono dettagliati il sistema modulare, il meccanismo a percussore lanciato e le sue sicurezze intrinseche, confrontandolo con altri sistemi come il Safe Action. Vengono inoltre presentati test pratici per verificare l'engagement del Sear e la disconnessione, sottolineando l'importanza della manutenzione e del buon maneggio per garantire la sicurezza.

This video clarifies that striker-fired pistols are not inherently unsafe, but rather explains the mechanics that can lead to unintended discharges under specific conditions. It debunks common misconceptions about trigger and striker safeties, emphasizing that the core issue often relates to slide-to-frame tolerances and sear engagement. The speaker, an experienced firearms instructor, uses examples from Glock and Sig P320 to illustrate these points, stressing that invalid testing methods can lead to misinformation.

This guide details a demonstration of potential 'uncommanded discharge' in a Glock 19, using a cutaway model and a mechanical trigger stop. The expert instructor visually explains how jarring the slide can cause the striker to release due to specific sear engagement tolerances, a phenomenon also observed in other striker-fired pistols. The demonstration emphasizes understanding the mechanical function of striker-fired systems.
