Why The US Army REALLY Said NO To Glock!
The US Army rejected the Glock 19X for the XM17 trials primarily due to a lack of true modularity and the added cost of a thumb safety. The Army required a system capable of transitioning between full-size, mid-size, and compact using a single serialized part, a feature the Sig Sauer P320 (M17/M18) achieved through its removable trigger group. Glock's solution would have necessitated purchasing multiple separate firearms, making it less cost-effective than Sig Sauer's modular approach.
