10mm is the Best Millimeter: the Colt Delta Elite
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.
