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.
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.
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.
