No, the NY trigger springs are an option as far as I know. The best way to do this is to order your pistol with a standard 5lb connector, then pick up all the other connectors & springs from us. Now you can change it all around to suit your taste!
A standard trigger spring is 5lb, Wolff trigger spring is 6 lb, NY trigger springs are available in 8lb or 12lb. Standard connectors are available in 3.5, 5, 8.
You can mix the springs with the connectors until the cows come home and custom design the best trigger system for yourself. Its EASY!
The only combination that will not work is a 8lb connector with any NY trigger spring.
