Is 5.7x28mm Just Overpriced .22 Magnum? [Part 2]

The KelTec PR57 revives the stripper clip-fed, fixed internal magazine concept for a modern 5.7x28mm concealed carry pistol. It offers a high capacity of 21 rounds in a remarkably thin and lightweight package, weighing only 13.86 oz unloaded compared to a Glock 19. The firearm demonstrated exceptional reliability with zero malfunctions across hundreds of rounds and features a unique manual of arms and rotating barrel lockup.

This video investigates the terminal ballistics of .22LR at point-blank range, specifically its effectiveness as an 'assassin's bullet'. Experiments using a ballistic dummy head reveal that hollow-point .22LR rounds, like the CCI Stinger, create a contained, muffled shot with no exit wound, trapping evidence. Ball rounds, such as the CCI Mini-Mag, produce a louder report and an exit wound, allowing pressure to escape.

This YouTube video compares the Smith & Wesson M&P 5.7 and the M&P .22 Mag, highlighting their shared frame design while showcasing the differences in their calibers. The description emphasizes that the video is produced for documentary and educational purposes, filmed in a safe and controlled environment. It also includes information for supporting the channel and sending fan mail.

This video provides a comprehensive review and evaluation of 5.7x28mm pistols, addressing their value and practical applications. It compares them to popular calibers like 9mm, discussing performance aspects such as recoil, accuracy, and ballistics. The content also covers ammunition availability and cost, and highlights specific models like the FN Five-seveN, Ruger 57, and PSA Rock. The aim is to help viewers determine if a 5.7 pistol is suitable for self-defense, range use, or collecting.

This review tests the lethality of tiny pistols, specifically the Smith & Wesson Bodyguard 2.0 in .380 Auto and the Standard Manufacturing Switch Gun in .22 Magnum, against ballistics gel. Results show .380 Auto performance is nearly identical to 9mm, and .22 Magnum achieves over 12 inches of penetration, demonstrating that small firearms can be effective for self-defense.

This video tests M855 Green Tip 5.56mm ammunition in ballistic gel, demonstrating its terminal ballistics. The 62-grain projectile creates a significant wound channel, expanding to 2 inches after 3 inches of penetration. While M855A1 has replaced it for some professionals, M855 remains available to civilians.

Chris Baker of Lucky Gunner Ammo explains the 'Cruiser Ready' method for storing a home defense shotgun, balancing safety and accessibility. This technique involves a loaded magazine tube but an empty chamber, with the safety off and action unlocked. This allows for rapid deployment by simply racking the slide. Baker also advises loading the magazine one round shy of capacity to preserve magazine spring longevity and prevent potential failures.

The FBI's brief adoption of the 10mm Auto in 1989, primarily with the Smith & Wesson Model 1076, proved disastrous due to mechanical issues and complexity. This led to the development of the '10mm Lite' and ultimately the .40 S&W cartridge, which was quickly adopted by Glock and dominated law enforcement for decades. The 10mm Auto's potential was recognized, but its practical implementation by the FBI failed.

The Ruger Mini-14 has maintained popularity for nearly 50 years by filling a market gap for an affordable, practical semi-automatic rifle, drawing inspiration from the M14. Despite early accuracy criticisms and political controversies, design updates and competitive pricing have kept it relevant, though the rise of affordable AR-15s presents new challenges.

This review of the Chiappa 1892 Alaskan Takedown lever-action rifle highlights its unique takedown feature, making it highly packable. Chris Baker of Lucky Gunner Ammo details its design evolution, caliber options (.44 Mag, .357 Mag), and compares it to other takedown lever actions. While praising its smooth action and crisp trigger, Baker notes some cosmetic quality control issues and suggests ergonomic modifications for improved handling. The rifle demonstrated 100% reliability over 300 rounds with good accuracy from premium loads.
