I guess the real question is single or two stage trigger. Which one is better for silhouette and what exactly are the differences? I've googled it and came up with 2 stage having let up while one stage is no let up and shot fired immediately... not to sure though. What can you guys let me know?

Wills, I believe the CZ 453 has a set trigger that can't be used in Silhouette. My suggestion is a 452 with a Timney trigger.

A single stage trigger in hunter would require 2+ pounds of pressure to make it go 'BANG." A 2 stage trigger would require about 1.5 pounds to take up the first stage and then only about 0.6 pounds to make it go 'BANG."
