Lightening a Sigma trigger

Is there a way to reduce the weight of the Sigma trigger pull?

Don't.

There's some things you can do. Check www.smith-wessonforum.com for details, but you could replace with a weaker striker spring (Wolff sells such a unit) and, there's a spring in the trigger group you can remove. BUT, I have to agree with the post above: leave it be. These two mods can affect the reliability of the gun and have no place whatsoever on a gun maintained for defensive purposes. It will smooth up a bit on its own after a thousand rounds or so. This will give the impression of a lighter pull. There's no reason why the factory stock trigger on these guns can't be mastered. Just takes a bit of practice. Want a better trigger? Ger an M&P.

Place a "For sale" sign right next to it.

So why is it a bad thing to do?

Midway sells the reduced power striker spring and IMO, it really makes a difference on the Sigma's.

If you use your Sigma for SD and want to modify the trigger, my only suggestion would be to test with your desired carry ammo. This should be done anyway, whether you have mods or not.

I put the Wolff reduced power striker spring in my SW40F and have not had any problems lighting off the primers on any factory .40 ammo for SD.

I suppose you could potentially have problems in 9mm if you were using a military spec round with primers a bit on the harder side. But, would that be your first choice ammo for SD use?

I think the spring is $4-5, so it won't cost you much to try it and see if it works for you and our ammo.

So the difference in the stock vs lighter pull is in the striker spring? This would just be a range gun.

I wouldn't say all the difference is in the striker spring, but I think you will find that it is easier to pull the trigger and compress a lighter weight striker spring than it is a heavier one. It isn't going to magically turn your Sigma into a bullseye gun, but you should feel a noticeable difference.

Much like Glocks, there are ways to further reduce/alter the trigger pull by replacing other trigger springs, but no one makes any that I am aware of (at least like they do for Glocks).
