Since I started reloading, I've been taking the 65 to the range more these days, and although the trigger is pretty smooth I'd like to lighten the DA side of things. The gun is 100% bone stock and I don't want to make any mods other than springs so it can be returned to stock if I ever want to do so. I see Wolff makes a set (below link) that are for the 65, among others, but will these fit the older models? Read all the reviews, sounds very promising. Thanks.
