Frequently Asked Questions

What makes the Colt Delta Elite unique for the 10mm Auto cartridge?

The Colt Delta Elite features a dual nested recoil spring and a polymer buffer to manage the 10mm's power. It also has a specific frame rail cut-out to prevent stress fractures, a modification later adopted by Colt for all 1911s.

When was the Colt Delta Elite introduced and what was its significance?

The Colt Delta Elite was introduced in 1987 as Colt's response to the emerging 10mm Auto cartridge. It was the second production 10mm pistol, following the Bren Ten, and successfully adapted the 1911 platform to this powerful caliber.

How does the Delta Elite's magazine differ from a .45 ACP 1911 magazine?

Due to the narrower diameter of the 10mm Auto cartridge compared to the .45 ACP, the Delta Elite's magazine incorporates internal indents. These indents ensure the cartridges remain properly centered for reliable feeding.

What historical context surrounds the 10mm Auto cartridge and the Delta Elite?

The 10mm Auto was championed by Jeff Cooper for its power. While the Bren Ten initially introduced the caliber commercially, it faced commercial failure. Colt's Delta Elite then successfully brought the 10mm to a wider audience by adapting their proven 1911 design.
