Hwansik Kim’s USPSA Limited Optics Gun

This video details the process of cleaning Glocks that have reached a point of malfunction due to extreme round counts and neglect. Ben Stoeger explains that his Glock 47s, with tens of thousands of rounds each and aftermarket Apex triggers, eventually stopped functioning reliably in cold weather and with lighter ammunition. He describes field stripping, cleaning slide rails, and addressing striker channel issues as necessary steps when firearms reach this state.

This video by Ben Stoeger explains the concept of 'input' in firearm manipulation, differentiating it from grip. It emphasizes that proper return to target is achieved through controlled input from the arms, not just hand pressure. Stoeger demonstrates how different firearms, from Glocks to a compensated Staccato, require varying amounts of input to return to the point of aim, advocating for 'less is more' to achieve consistent accuracy.

This video discusses the perceived benefits and popularity of compensators and ports on firearms. While acknowledging they offer a noticeable reduction in muzzle rise (estimated around 20%), the speaker suggests their primary appeal lies in the dramatic, aggressive feel and marketing appeal rather than a fundamental change in gun dynamics. The discussion highlights how these features cater to consumer desire for modularity and 'extra' features on popular platforms.

This video provides expert advice from a seasoned infantryman and firearms instructor on building a practical, mission-focused firearm collection. The instructor advocates for avoiding 'fudd guns' like revolvers, pump-action shotguns, bolt-action rifles, and lever-action rifles in favor of modern, reliable platforms. The core recommendation is to standardize on a few reliable pistol and rifle platforms, emphasizing 9mm handguns (specifically Glock variants) and AR-15s in common calibers and barrel lengths, to maximize training efficiency, parts interchangeability, and overall preparedness.

Joel Park, a USPSA Grand Master, emphasizes the critical need for specialization to achieve elite performance in competitive shooting. He explains that while fundamentals are transferable, mastering the unique nuances of grip pressure and recoil for a specific platform is essential for championship-level success. Park advises dedicated training with identical setups and warns against diluting focus across multiple disciplines if a high rank is the ultimate goal.

Joel Park, a professional firearms instructor, details methods for accurately assessing pistol index. He emphasizes isolating the draw and presentation from the trigger press to identify true index errors versus marksmanship faults. The guide includes drills for both index and trigger control, highlighting how equipment like custom triggers can influence training.

Lucas Botkin, founder of T.Rex Arms, shares his expert insights on optimizing carbine builds based on extensive round counts. He details his philosophy on barrel length versus optic choice, preferring red dots for shorter barrels and magnification for longer ones. Botkin also discusses preferences for muzzle devices, foregrips, lights, lasers, and triggers, emphasizing reliability and simplicity for high-volume use.

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 practical considerations of Short Barreled Rifles (SBRs) with firearms instructor Nick Young. Key takeaways include the benefits of SBRs for suppressor use, the legal complexities involving ATF travel paperwork, and the potential reliability issues and increased violence in shorter-barreled platforms. The discussion also touches on the importance of proper buffer systems and the tendency for 'Franken-guns' to fail in training.

Hwansik Kim explains his 'No Friction Grip' technique, developed to maintain control in adverse conditions like sweaty hands or rain. The method emphasizes specific pressure points, particularly using the support hand's index finger on the trigger guard and the top knuckles of the support hand on the firing hand. This technique aims to minimize reliance on grip enhancers and provide consistent control through recoil by creating a stable platform without excessive friction.
