The US military's transition to 9mm ammunition, initially in the 1980s and continuing with the Sig P320, was driven by several key factors. These include standardization with NATO allies, logistical advantages like reduced weight and cost, increased magazine capacity, and practical effectiveness demonstrated by faster follow-up shots. The military's use of ball ammunition, due to war crime regulations, is a significant consideration.
This video from Boondock Ballistician delves into the 5.7x28mm cartridge, exploring its history, technical evolution, and performance against competitors like 9x19mm NATO. The instructor, demonstrating high authority, analyzes ballistic data and discusses the challenges of reloading this specialized round. Key takeaways include the cartridge's development for armor penetration, its trajectory advantages over 9mm, and the complexities of its case design for handloaders.
The US military's decision to adopt 9mm ammunition for sidearms, initially in the 1980s and continuing with the Sig P320, was driven by several key factors. These include standardization with NATO allies, logistical advantages like lighter weight and lower production cost, increased magazine capacity, and practical effectiveness, which emphasizes faster follow-up shots and more hits on target for the average soldier compared to larger calibers like .45 ACP. The recent adoption of the Sig P320 highlights continued adherence to these principles, with modularity being an added benefit.
The US military's transition to 9mm ammunition was driven by several key factors, primarily standardization with NATO allies who predominantly used 9mm handguns like the Browning High Power. Logistical effectiveness, including lower production costs and lighter ammunition to carry, also played a significant role. Furthermore, the 9mm caliber offers higher magazine capacity compared to older service calibers like the .45 ACP, and studies indicated that soldiers, particularly those with less extensive firearms training, could achieve faster follow-up shots and place more rounds on target with 9mm handguns, contributing to practical effectiveness.
This Q&A session with Ian McCollum of Forgotten Weapons covers a wide range of firearms topics, from historical Finnish Mosins and the evolution of NATO cartridges to modern firearm development and controversial designs. McCollum discusses the provenance of Finnish Mosins, the rationale behind NATO's cartridge standardization over rifle standardization, and the technical challenges of advanced grenade systems like the XM25. He also touches on the viability of various pistol and rifle designs, the future of ammunition, and the durability of classic machine guns like the Maxim.
The US military's transition to 9mm ammunition was driven by several key factors, primarily standardization with NATO allies who widely adopted the 9mm cartridge. Logistical benefits, including lighter ammunition and lower production costs, also played a significant role. Furthermore, increased magazine capacity and the ability for soldiers to achieve faster follow-up shots with 9mm handguns, particularly for less experienced shooters, were crucial considerations. This decision has persisted even with the adoption of new platforms like the SIG Sauer M17/M18.
This video details the US military's XM9 trials, which selected the Beretta 92FS (M9) as its service pistol. It contrasts the rigorous, multi-phase testing process with the flawed XM17 program, emphasizing that the XM9 selection was based on exceeding stringent criteria, not solely on the lowest bid. The program involved extensive reliability, durability, and corrosion testing, with both the Beretta 92FS and SIG P226 emerging as top performers before a final competitive bidding process determined the winner.
This video provides an in-depth look at the Heckler & Koch G41, a rifle developed in response to NATO standardization efforts and the US Squad Automatic Weapon program. Expert Jonathan Ferguson details its roller-delayed blowback operation, its adoption of AR-15 pattern magazines, and features like the bolt hold-open and forward assist, comparing it extensively to the HK33 and AR-15.
This video provides an in-depth look at the Beretta AR70/90, an Italian military rifle. It details the rifle's development post-WWII, its technical specifications, and a comprehensive disassembly and reassembly process. The presenter highlights key features like its stamped receiver, long-stroke piston system, and its evolution from earlier Italian designs to its eventual replacement by the ARX160.
The Heckler & Koch G11 was a revolutionary bullpup rifle developed for the Advanced Combat Rifle program, aiming to increase hit probability through innovative features like caseless ammunition and a high rate of fire. Despite its advanced technology, including a unique rotating bolt and caseless ammo that left no spent brass, the G11 was not adopted due to several factors. These included the complexity of its internal mechanisms, the fragility and environmental sensitivity of its caseless ammunition, and geopolitical shifts that altered military spending priorities. The US military's general aversion to bullpup designs and existing investment in 5.56 NATO ammunition also played a role in its ultimate rejection.
This video from Classic Firearms delves into the historical reasons behind NATO's adoption of the 7.62x51mm cartridge. Experts discuss its development from .30-06 Springfield, the political maneuvering involved in its standardization over alternatives like the .280 British, and its eventual replacement by 5.56 NATO in many roles. The discussion also touches on the modern shift towards cartridges like the 6.8x51mm (.277 Fury) for the Next Generation Squad Weapon program.
This video critically examines the US military's adoption of the Sig Sauer XM5 (M7) rifle and the 6.8x51mm (.277 Fury) cartridge, questioning the logistical feasibility and practical combat effectiveness due to significant recoil and muzzle climb observed in early testing. The analysis, presented with high authority by the Military Arms Channel, delves into the technical challenges of extreme pressure rounds, potential barrel life reduction, and the high cost of new optics like the Vortex XM157, while also considering the strategic goal of defeating advanced body armor.
