Default 4586 trigger pull

Last year I purchased a 4586 from Bud's. Pistol is awesome but I would like to know if anything can be done to the trigger. The pull is somewhere around 8-10 lbs. Can anything be done to lighten it up and still function? Otherwise it is a great gun.

Thank you in advance.
Charlie

Hey Charlie. I just saw your post (was cleaning my 4586 last night) and have a possible answer. If you replace the factory 20# hammer spring with a Wolff reduced power hammer spring it will lighten up the pull. The 3 pack comes with three springs (16, 17, 18#) and if I recall correctly (I'll have to check) I replaced the factory spring with the lightest one of the three, the 16#. It lightens it up quite a bit with no other effects on the trigger. Of course, when you lighten a hammer spring you will want to be aware of the possibility of light primer strikes on some ammo's primers and check for this with any ammo that might be used. To date I have not experienced any light primer strikes. Even if you go with the two less reduced springs you will see an improvement.

I really like the DAO trigger on the 4586 and the Wolff reduced power spring only makes a very nice trigger that much better. As you know it's a nice smooth short stroke with a short reset.

Correction: My Wolff reduced power spring is a 17#. Now I'm tempted to try a 16#.

The other thing you might want to do is replace the trigger return spring with a reduced power spring and not go as light on the hammer mainspring to hedge bets on potential light primer strikes... you're also working against the spring tension of the trigger return spring when pulling the trigger rearward.

In my 1006 a 2.5 lb wolf return spring reduced the DA and SA trigger pull by about 1 lb alone - I know the OP's gun is DAO only. My comment is just for reference.

Cool

As it turns out it is the 16# hammer spring. Just to compare I put the old factory 20# spring back in and the 16# is big time significantly better. But again, light primer strikes should be ruled out as a possibility.
