Quick Tip: 10mm Auto vs .40 S&W - What's the Difference?

The 10mm Auto, initially powerful, proved problematic for the FBI due to recoil and wear, leading to the development of the reduced 'FBI load.' This compromise eventually resulted in Smith & Wesson shortening the case to create the .40 S&W, fitting it into 9mm-sized frames. The video details the S&W 1076, an FBI-adopted pistol featuring a frame-mounted decocker and single-stack magazine.

This review of the Smith & Wesson M&P 2.0 in 10mm highlights its robust features, including a ported barrel, Picatinny rail, and optics-ready slide. The pistol offers a 15-round capacity and is presented as a controllable yet stout option suitable for both backwoods protection and personal defense. The instructor emphasizes choosing a firearm you can shoot accurately.

This expert-level review details the FBI's rare 10mm MP5, exploring its origins after the 1986 Miami shootout and its adoption alongside the Smith & Wesson 1076. It highlights the MP5-10mm's exceptional accuracy and tactical advantages in CQB and vehicle operations, as shared by former FBI agents. The review concludes with the reasons for its eventual phasing out in favor of M4 carbines due to evolving threat landscapes and cartridge limitations.

This video from ClassicFirearms presents a 'Top 5' list of pistols not chambered in 9mm, featuring selections from both Jason and Eliza, a firearms instructor. The discussion covers a diverse range of calibers including 10mm, .22LR, .380 ACP, .40 S&W, and .45 ACP, highlighting each firearm's unique strengths for various applications like concealed carry, training, and personal defense. The hosts offer insights into recoil management, capacity, ergonomics, and specific use cases, encouraging audience engagement.

This video from Kentucky Ballistics delves into the history and performance of Winchester's controversial Black Talon ammunition. Host Scott debunks myths about the ammunition being banned, explaining it was voluntarily withdrawn from the civilian market due to public pressure. Through extensive ballistic gel and body armor testing across various calibers, the video demonstrates the actual penetration and expansion capabilities of Black Talons, concluding they were not armor-piercing for handguns and were later rebranded as Ranger SXT.

This video features Mr. Madness conducting an ice penetration test comparing seven different calibers from .22LR to suppressed 5.56 NATO. The test visually demonstrates the significant increase in penetration power and ice displacement as caliber increases, with the 5.56 NATO round creating the largest crater. The host provides a clear, comparative analysis of each caliber's impact.

This video details the installation of a Geissele MK8 Super Modular Rail on an AR-15. Key steps include using a Geissele Reaction Rod for upper receiver stability, proper torquing of the proprietary barrel nut, and secure installation of the gas block and tube. The rail is then slid on and secured with two cross-bolts using a T-handle hex wrench. Final steps involve muzzle device installation and a thorough inspection.

Proper ammunition storage is crucial for maintaining reliability and safety. Avoid storing ammo in cardboard boxes in damp environments, as this leads to moisture absorption and corrosion. Utilize airtight containers like ammo cans and control humidity with desiccants like silica gel packs. Heat accelerates gunpowder and primer degradation, so store ammo at stable room temperatures. Reloading primers are particularly vulnerable to moisture and require strict airtight storage.

This video demonstrates how to upgrade an AR-15's A2 furniture to Magpul components. It details the removal of the A2 grip using a Bondhus hex set and the installation of a Magpul MIAD grip with interchangeable backstraps for improved ergonomics. The process also covers preparing and installing the Magpul PRS stock, highlighting its adjustable features for cheek weld and length of pull.

This video explores the custom Remington 11-87 shotgun used as a prop in 'No Country for Old Men.' The film required a semi-automatic shotgun with a suppressor, a combination not readily available at the time. Prop master Larry Zanoff details how a non-functional, 'homemade' looking suppressor was custom-built for the 11-87, with the iconic silenced sound effect achieved entirely in post-production.
