S&W Sigma 9mm Trigger question.

[SCBaldr]

I know I could take my new S&W Sigma to a gunsmith and ask for a trigger improvement and when said gunsmith was finished with it, it would have a much nicer 6 pound DAO pull than the current 8-12 pound DAO pull. I don't really feel like spending a bunch (or any) money on a gunsmith for something that seems like a simple enough procedure.

Does anyone have instructions for how to work the trigger on this model of S&W? Which, if any, parts do I need? Any help would be appreciated.

I'm one of the few people who don't have a problem with the trigger pull on the Sigma series. I had both a SW9VE and a SW40VE but have sold them cause of financial reasons. I put about 500 rounds through each gun and noticed a big difference in the trigger. Was smoother and shot better. I also liked the heavy trigger cause it doesn't have a safety.

Just my two cents.

I was looking at the Sigma series a year ago. In hunting for comments about the gun I saw a post somewhere that stated that S&W would adjust the trigger pull for free. I don't remember what he said about shipping. I didn't see anything on there website, but I would contact their customer service department and check. That was the only negative I ever read about the Sigma's was the trigger pull being heavy.

Here is what i used. i also have a detailed version, too large to attach here, i will send it to you PM if you need it.
don't be afraid, very easy, and remove the 2 springs, i love the trigger pull now.

[SCBaldr]

I think the trigger is going to stay in stock form for the first 500 rounds. That was a good piece of advice, I should have had the sense to give myself. After that, if I think it still needs a big improvement, I'll do the spring removal mod. Instead of removing the outer spring entirely, is there a lighter spring one can substitute? I'm going for a pull of around 6 pounds.

[tonyfac]

the only reason that the 2 springs were there was from the lawsuite filed by glock over this design, part of the settlement was the addition of the 2 springs. take them both off and you have about a 5lb pull. do not remove just one, gets squishy.

I've cleaned up a bunch of Sigma triggers. Just dump those two springs and don't worry about a thing. There is also a small casting line on the plastic sear carrier that can be smoothed off.

After that, we go into striker springs and polishing......

I shot a sigma with maybe 50k rounds through it (rental range whore gun) and it had one of the nicest triggers in a plastic pistol! almost convinced me to buy one instead of a walther p99.... almost

Could u send me the more detailed version? In the seven yrs I've had my SW9VE, the trigger has eased up but my carpal tunnel has gotten worse.

In addition to What the others have said, Wollf sells a spring kit for the Sigma, think i paid about $10 years ago , works wonders with the Sigma trigger
