The Delta Elite is the gun that helped launch 10mm into the mainstream. Colt's Delta Elite was the first 10mm pistol from a major manufacturer when it launched in 1987 — Dornaus & Dixon's Bren Ten predated it (1983), but only about 1,500 were ever made before the company went bankrupt, and the Delta Elite is the gun that gave 10mm commercial staying power. The current version keeps the same basic formula: a full-size stainless 1911 with a 5" barrel, 8+1 capacity, and a 35 oz loaded weight. That all-steel construction is the point. Full-power 10mm loads generate serious slide velocity in polymer guns, and the Delta Elite's stainless frame soaks up more of that energy than the 28.4 oz Glock G20.

The single-action trigger breaks at 5 lbs, which is heavier than the Dan Wesson Bruin's 4.2 lb pull but about average for a production 1911. Colt fits Novak Low Mount Carry sights from the factory, a sensible choice for a gun likely to ride in a chest rig or belt holster in the field. There is no optic cut and no rail, which limits accessory options but keeps the slide profile clean. The three-safety system (thumb, grip, firing pin block) is standard 1911 architecture, and Colt adds a Series 80 firing pin block that some owners dislike for its effect on trigger feel.

Buy the Delta Elite if you want a traditional 1911 in 10mm with Colt's name on it and enough weight to tame full-power loads. Skip it if you need more than 8 rounds or want to mount a red dot. The Sig P320 XTEN carries 15 rounds and ships optic-ready, and the Springfield XD-M Elite holds 16 rounds at 31 oz.
