9mm vs 10mm vs sheet metal

This video explores the growing trend of shooters replacing 9mm with alternative calibers in 2025, driven by advancements in ammunition and firearm technology. The presenter, Ted from Line 45, details the strengths of .30 Super Carry for concealed carriers seeking higher capacity in compact frames, 5.7x28mm for its flat trajectory and speed, 10mm for its significant power and barrier penetration, .357 SIG for its velocity and hard target performance, and .22 TCM for its rifle-like speed in a pistol platform. The discussion highlights how these calibers address specific needs that 9mm may not always meet, emphasizing performance, capacity, and specialized applications.

This video explores the practicalities and perceived importance of having a handgun and rifle that share the same ammunition. While acknowledging the convenience factor, the presenter argues that it's often overrated and can lead to compromises in firearm selection, particularly for hunting or specialized roles. The discussion touches on historical contexts, modern applications, and potential scenarios like the apocalypse, ultimately suggesting that distinct calibers for handguns and rifles can be more advantageous.

This video argues that revolvers often outperform semi-automatic pistols for bear defense due to their reliability and simplicity, even though semi-autos offer higher capacity. The speaker emphasizes that in a bear encounter, capacity is irrelevant as a charging bear will likely be engaged within one or two rounds. The focus should be on caliber, capability, ease of use, and accuracy, areas where revolvers are considered superior for this specific application.

This review covers the Nanorroni PCC conversion kit for Glock pistols, specifically demonstrating its use with a Glock 19X. The kit transforms a handgun into a pistol carbine, significantly improving stability and target acquisition speed. It is compatible with a wide range of Glock models and offers features like an integrated magazine holder and an optic mounting platform.

Ted from Line 45 discusses the evolving landscape of handgun calibers, highlighting how shooters are increasingly looking beyond 9mm for specific needs. The video explores 30 Super Carry for increased capacity in compacts, 5.7x28mm for flat trajectory and speed, 10mm for significant stopping power, 357 SIG for barrier penetration, and 22 TCM for rifle-like velocity in a pistol platform. The discussion emphasizes that while 9mm remains a standard, newer calibers offer solutions for specialized applications.

This video explores ten significant upgrades for Glock pistols, focusing on enhancing performance and customization. It details the Glock Performance Trigger, Trijicon RMR Type 2 optic, various aftermarket sights, Talon Grips, and the Streamlight TLR-1 HL weapon light. Additionally, it covers several Glock models including the G49, G19 Gen 5 MOS, G20 Gen 5, G43X MOS, G30SF, G17 Gen 5, and G44, highlighting their specific features and use cases.

This video features Edwin Sarkissian, an experienced firearms instructor, conducting a unique bullet penetration test. He uses 12 Ozark Trail 12-inch cast iron skillets to determine how many rounds from various calibers and firearms, including 9mm, .45 ACP, 500 S&W Magnum, 7.62x39mm, 5.56mm, 5.7x28mm, and 12 Gauge slugs, can penetrate the cookware. The results offer practical insights into the ballistic performance of different ammunition types against a common household item.

This video from Edwin Sarkissian provides an expert-level demonstration of the Serbu BFG-50A rifle's capability against a railroad track. Sarkissian, a high-level firearms enthusiast, showcases the .50 BMG caliber's power with various ammunition types, including the specialized Raufoss Mk 211 Mod 0, highlighting its penetration through thick steel. The content offers valuable insights into terminal ballistics and the performance of heavy caliber rounds.

This video demonstrates a unique application of the X Products Can Cannon, a gas-operated launcher compatible with AR-15/M16 lowers, to launch an M67-style fragmentation grenade using .223 Blanks. Expert experimentalist Edwin Sarkissian showcases the process of loading and firing the device towards a frozen lake, highlighting the launcher's ability to hold the grenade's spoon in place until firing. The demonstration results in a significant explosion and ice shatter upon impact.

This guide details a ballistic test comparing a .50 Cal Spotter round against a 1.25-inch thick bulletproof glass panel using a Serbu BFG-50A rifle. The test, conducted by firearms enthusiast Edwin Sarkissian, demonstrates the significant destructive potential of specialized .50 BMG ammunition, highlighting differences in impact effects between incendiary spotter rounds and standard FMJ rounds. The expert-level demonstration emphasizes the importance of understanding ammunition types and their performance against protective materials.
