Default 4586 Trigger

Anybody know if there is a way to lessen the tension of the trigger for a 4586? If so, is it something that the ordinary joe can accomplish?

You mess with a trigger, you'd better know what you're doing.

Can the tension be reduced without compromising the effect of the firing pin?

Try searching for Wolff springs. Some folks have used 17# hammer springs along with 2.5# trigger springs. The hammer spring is easy. The trigger spring requires disassembly which is covered on this forum. It's easy too, but a little complicated.

Do you know...are those proper terms if I were to search for the parts at an online gun parts site? I've seen the term "sear spring" but I don't know if that's the right part.

Here's a link to the Wolff site.
Springs for SMITH & WESSON NUMBERED SERIES Semi-Auto Pistols

Here's a pic of the Sear Spring. No need to change it unless it's bent way out of spec. When I disassemble my Gen 3 pistols I don't even remove it.


The most common spring to replace is the Main Spring to improve double action pull, Hammer Spring on the Wolff site. Easy to change, just remove the grips.


You can also lighten the double action pull by putting in a lighter Draw Bar Plunger Spring, Wolff calls it the Trigger Return Spring. Trouble is you have to take the pistol apart.

Here's what it looks like from the top of the frame, pistol assembled.


And how you'd see it disassembled.
.

I would try the lighter Hammer Spring first. Get several weights and make sure that you don't go so light that you get light primer strikes and a useless pistol.

While you're at it, get several weight Return Springs. Even if you don't use them, they don't cost much and it will save you shipping if you want them later.

Good Luck

Dave
