I have 2 S&W 9mm pistols. I have a 669 and I love it.
But I also have a Sigma sw9ve and the trigger pull is very difficult to manage. It pulls back about 75 percent smooth as butter, then it has a really hard pull till it breaks and fires.

I took it to a gunsmith here and he said it is an inherent issue with the Sigma's. He said it's part of the safe firing system and can't be adjusted.
It's hard to believe that S&W would intentionally build a pistol with a pull as hard as this has.

The accuracy is okay as long as you are only shooting one shot at a time and adjust for the rise because of the pull. NOT!

Any ideas or suggestions

I just got mine and havent even shot it yet, just dry fired it and my trigger feels slightly gritty but is the same all the way through. Smooth but gritty if that makes any since. Also I heard some people say that the time of detonation is unpredictable but I can predict it every time. Maybe try polishing the sear and putting on a thin film of grease.

I replaced the stryker spring and did the trigger work on this post. S&W Sigma pistols, (SW9VE) trigger job - Georgia Outdoor News Forum

Did you just get this gun new? Mines got easier to pull after a few hundred rounds. A few guys on here has sent theirs back to S/M for a free trigger job. I'm going to do that when I get another full sized pistol.

Send it back to S&W. They will make it right and safe.

Ok TC just did the trigger job that hoochfisher posted on GON and it was a cakewalk. Let me just say that this is the first time I have ever done any gun smithing and I was a little hesitant at first, until i figured out that there isn't really much to these guns at all. You should try it, and if you dont feel comfortable then I recommend you do what others suggested and send it off to have it smoothed out a bit.

The pistol is almost new, I've fired only 50 rounds or so thru it.
I guess I need to get it fixed. I'll try the earlier post on how to adjust it. If it's too detailed I think I'll just send it out to S&W to get the trigger job done.

Thanks for all the help.

If you decide to send it off, send it to LSG Manufacturing. They are a factory authorized warranty repair center in Texas. Their name and address are on the back page of your owners manual.

I sent my SW9VE to Frank Smith, the owner, on a Saturday and had it back the following Thursday! On top of that, he apologized for taking so long!

Scott

Is Frank the owner of LSG?
Should I send it to him directly?

Yeah! LSG. Call them first. Frank has a standing account at FEDEX if I'm not mistaken. Shouldn't cost you anything.

I'd skip the grease and follow S&W's lube instructions.

I might just mention that if you are going to use this as a defensive carry gun, or even a home protection gun, that you forego the shadetree mechanic gunsmithing on the trigger and either leave it stock, or only get it worked on by a factory authorized servicer. There is too much liability involved with internet "fixes" for the firing mechanism on a pistol, especially "fixes" that have total disregard for factory design and specifications.

Quite frankly, the Sigma was intentionally designed with a long, fairly hard trigger pull (about the same as a double-action revolver). With a little practice, it is relatively easy to master. I get along with both of mine just fine.

I agree with CSHOFF. I forgot to ask if it was for defense carry or target practice. Ill be using mine for training and target practice only as I have an 870 12 gauge for home defense.

Target practice only. I'm pretty sure I'm going to send it out, to at least see if it can be improved.

Thanks for all the help

Send it out and be safe. Let us know how you make out.
My trigger was 200% better after I sent it out compliments of S&W.

In that case, I second the recommendation to send it to Frank Smith at LSG Manufacturing. First class operation, all the way around.

Frank Smith at LSG Manufacturing did a good job on mine. I was having failures to feed on it and I sent him the gun. Smith and wesson paid for the shipping there. Also, I advised him that my trigger felt gritty and was hard to pull and asked him to polish the sear and trigger bar. I am not sure what he did but two days later I got the gun back from him and the trigger was as smooth as glass. I had already had another gunsmith install the 3.5 pound striker with which I never had problems. He put on the repair ticket he adjusted the trigger bar and adjusted the sear. It definitely does not look like the trigger bar is rubbing up against the frame anymore. There was no charge for this at all and smith paid for the return shipping. The failure to feed was due to a broken recoil spring on the guide rod which he replaced free of charge with a totally new guide rod. My lyman trigger gauge will be here next week and I will test the trigger pull on it and post back here. I can tell ya now though it feels 6 pounds or less. Before I sent it off when I would dry fire the gun or when I shot it with the laser when I pulled the trigger the shot would go down and to the left. Since the trigger adjustment the gun shoots dead on.

Have had mine for awhile, have put about 250 rounds, through it, and have dry-fired it quite a bit more, and either the trigger has smoothed out, or my trigger finger has gotten stronger. Goes to the range almost everytime, very enjoyable to shoot.

I sent my Sigma 40 ve to Mr. Smith last summer and he fixed it Right. My breaks at 5.5 pounds. Smooth as butter just like a S&W should be.

Cost me the cost of the box.

After shooting my Kel-tec, you will LOVE the trigger on our Sigmas.....

I bought my wife a Kel-Tec P11 . . . she can NOT fire it; trigger pull is tooo long and tooo hard. She has no problem (well not much anyway) firing my SW9VE. When I first got the Sigma, I thought the trigger was really bad; then I fired the P11 a few times-- the Sigma seems fine now.
