If Colt will furnish you with a wider trigger and that is your preference then that would be my choice. With my single action pistols I've never really had a preference one way or the other.
This happened to be a rather valuable New Zealand Red and I was feeding it carrots. Mistook my trigger finger for a carrot and nipped me. Later sold that rabbit for an airline ticket for my first airplane ride, on an American Airlines DC-3 Flagship, round trip Memphis to Nashville, non-stop.My first thought would be to wear gloves when you handle a rabbit. As to triggers, use whatever is more comfortable to you. Personally, since I don't shoot them excessively, I prefer original style triggers and hammers.
As to slip hammer shooting, no thanks. Even when plinking, I want hair-splitting accuracy.Or, one could remove the trigger altogether & work up a slip hammer (per Elmer Keith's book SIXGUNS) if the gun is intended for plinking or self-defense. Not good for bullseye target or long-range shooting though.
