Now We Know Why The US Army REALLY Said NO To Glock!

Duration: 8:04

The US Army rejected the Glock 19X for the XM17 modular handgun trials primarily because it did not meet the 'modular handgun system' requirement. While Glock offered interchangeable slides and grips, it did not present a truly modular system where a single serialized component (like the trigger pack) could be reconfigured into different sizes. The Sig Sauer P320, with its removable trigger pack, fulfilled this requirement, allowing for a single firearm to be adapted to full-size, mid-size, and compact configurations with additional modules, making it more cost-effective for the Army's large procurement needs.

Quick Summary

The US Army rejected the Glock 19X for the XM17 trials primarily because it did not meet the 'modular handgun system' requirement. Unlike the Sig Sauer P320, which uses a removable trigger pack for true modularity across different sizes, the Glock 19X's approach was deemed insufficient, and it was also significantly more expensive per soldier.

Frequently Asked Questions

Why did the US Army not select the Glock 19X for the XM17 trials?

The primary reason the US Army rejected the Glock 19X was its failure to meet the 'modular handgun system' requirement. While Glock demonstrated interchangeable parts, it did not offer a system where a single serialized component could be reconfigured into different sizes, unlike the Sig Sauer P320.

What were the key requirements of the US Army's XM17 modular handgun trials?

The XM17 trials demanded a 90% hit rate at 50 meters, improved ergonomics and recoil management, an accessory rail, ambidextrous controls, higher pressure round capability, and a mean time between failures of 10,000 rounds. Crucially, it required a truly modular handgun system.

How did the Sig Sauer P320 meet the modularity requirement better than the Glock 19X?

The Sig Sauer P320 features a removable trigger pack as the serialized component. This design allows users to swap grip modules and slides to create full-size, mid-size, or compact configurations from a single registered firearm, fulfilling the Army's modularity mandate.

Was cost a factor in the US Army's decision between the Glock 19X and Sig Sauer P320?

Yes, cost was a significant factor. The Sig Sauer P320 system, including modular components for multiple configurations, was estimated to cost around $1,100 per soldier. The Glock 19X system, requiring multiple firearms for similar configurations, was estimated at $1,800 per soldier.
