The SA trigger can't be too light for me ... just don't touch the trigger until you're ready to shoot. I normally use the minimum available rebound spring, which usually gives about a 2-1/2 to 2-3/4 trigger. When I carried my 10mm Kimber 1911, I had its trigger set to 2-1/4lb. For some reason, 2-3/4 lbs on my Model 69 feels LIGHTER than the 1911 trigger. My 629 has the next-stiffer rebound spring in it, because when the gun was new, the trigger wouldn't always return with the lightest rebound spring ... just some roughness in the works. So I think its trigger is about 3 lbs. It might work OK now with the lightest spring (because of all the live-firing and dry-firing I've given it has smoothed the works), but I haven't tried that, because the 3 lb trigger actually feels good enough.
