Delta Force STI 2011: Competition Meets Operations
This video details the US Delta Force's evaluation of the STI 2011 pistol in .40 S&W as a potential replacement for their .45 ACP 1911s in the mid-2000s. Alongside the Glock 22, the STI 2011 was tested but ultimately rejected due to magazine reliability issues. The 2011 platform's magazines, designed for longer .45 ACP cartridges, were too long for standard .40 S&W ammunition when used with firearms like the Glock. This prevented Delta Force from achieving ammunition standardization. The rejected STI pistols were later sold as used .40 caliber 2011s, with their unique provenance often unrecognized.
