I have two Colt Delta Elites. One is a stainless Gold Cup with target sites and the other is a blued model with 3-dot sites, flat top slide, arched main-spring housing, and lowered ejection port. I like both of them very much. The factory loads are plenty hot so I usually practice with a handload with Winchester nickel-plated cases and Hornady's 200 grain hollow point. I had been using Unique powder but I'm thinking of switching to either Longshot or 800-X. I put a Wilson one-piece guide rod, recoil buffer, and heavy spring in the blued model but have left the stainless gun untouched.
