Duration: 9:30

The Colt Delta Elite was Colt's 1987 answer to the 10mm Auto cartridge, adapting their Model 80 1911 platform. It featured unique red triangle grips and internal modifications like a dual nested recoil spring and polymer buffer to handle the 10mm's power. Early models experienced frame cracking issues, leading Colt to implement a frame rail cut-out solution.

Quick Summary

The Colt Delta Elite, introduced in 1987, was the second production 10mm pistol and Colt's adaptation of the 1911 platform. It featured a dual nested recoil spring and polymer buffer for recoil management. Early models faced frame cracking issues, leading to a frame rail cut-out solution.

Frequently Asked Questions

What made the Colt Delta Elite significant in the history of 10mm pistols?

The Colt Delta Elite was the second production 10mm pistol ever made, introduced in 1987. It was Colt's direct response to the emerging popularity of the 10mm Auto cartridge, adapting their iconic 1911 platform to this powerful new caliber.

What mechanical features did the Colt Delta Elite have to handle 10mm recoil?

To manage the increased power of the 10mm Auto, the Colt Delta Elite incorporated a dual nested recoil spring system and a polymer buffer. These components were designed to absorb recoil and control the higher slide velocity compared to .45 ACP variants.

What was the main durability issue with early Colt Delta Elite models?

Early production Colt Delta Elites were prone to frame cracking at the slide rails, especially when frequently fired with full-power 10mm ammunition. Colt addressed this by introducing a specific cut-out in the frame rail to relieve stress.

How did Colt modify the 1911 frame for the 10mm Delta Elite?

Colt adapted the standard 1911 frame for the 10mm cartridge by using a dual nested recoil spring and a polymer buffer to manage recoil. Crucially, they also introduced a frame rail cut-out to mitigate stress fractures caused by the powerful round.
