When I’m interested in powering up a handgun, downsizing the caliber is not my first thought. Yet, that’s the premise behind the 10 mm cartridge as envisioned by the FBI during its pursuit of the perfect pistol cartridge/caliber during the final decade of the last century. The bureau’s on-again/off-again romance with different solutions (along with Dornaus & Dixon’s failure of its Bren 10 pistol to reach production) essentially doomed the 10 mm until Colt stepped in and provided a home for the cartridge in the company’s iconic Model 1911.
Every time we hear the death knell of the 10mm cartridge, some manufacturer rolls out a new model to get fans of the round something to lust after and bring a few new converts its way. With this year being the 30th anniversary of the introduction of the Colt Delta Elite, Colt released the pistol in a rail gun format: Colt Delta Elite Rail Gun.
I used to follow the rule that a full-sized 1911 should be in .45 ACP. That rule doesn’t come from some religious belief (The Church of J.M. Browning has a lot of adherents), but rather from experience. The various full-sized 1911s chambered for other cartridges I have tried over the years just haven’t impressed me. But the Colt Delta Elite 10mm handgun is the one exception to that rule.
