My primary home defense weapon is a Beretta Model 96, hammer fired. I store it uncocked with a live round in the chamber and the safety off. On the first round I need a strong trigger pull to cock the hammer and then drip it. Then it cycles, reloads, and cocks itself. After that all I need is a relatively light pull on the trigger to fire the weapon.
Going to the Sig, if you start with a chambered round, does your first pull on the trigger cock the striker and then drop it, or is the weapon already cocked for that first shot, resulting in a much lighter trigger pull? Please pardon my ignorance.
Every trigger pull is SA light and identical. One of the nice features of not being DA/SA.
My DA/SA is just that, but you can cock prior to the first round if you choose.
