    I have read a lot of reviews and opinions about the Smith &Wesson sigma series weapons and the only real complaint that comes up is that the trigger is tough or even atrocious. I personally have a SW9VE and I couldn't be happier with the gun. In all honesty the trigger (as it comes from the Smith & Wesson) is tough. However with some smithing the problem can be completely removed. I had mine smithed by a gentleman named Tom Novak (http://www.handgunneroutlet.net./service/sigma.htm) and it completely alleviated the problem. The trigger from the manufacture is estimated to require between 8 to 12 pounds of pressure. With a simple and fairly inexpensive trigger job, I had mine brought down to around 4 pounds of pressure and it makes a world of difference. I understand why many people complain about the trigger as it comes from the manufacturer however the problem doesn’t warrant the reputation the NEWEST models of Sigma series have received especially when such an easy fix is so easily attainable.

    The most ironic part about the weapons is claims that S&W did a poor job with the weapon solely based upon consumer dislike of the trigger. THE TRIGGER WAS INTENTIONALLY MADE HARD! To cater to law enforcement requests, the sigma was equipped with a hard trigger to ensure safety. Because the weapon was Double Action Only, the hard trigger pull was requested and implemented to avoid accidental firing.

    Also anyone that claims that sigma series weapons aren’t target weapons should try firing one that has had a trigger job done and reevaluate their current opinion. The difference it makes is night and day. Smith & Wesson made another fine series with the sigma’s.

    Thanks JB!!
    I have an SW40F coming in and I think I will get the job done as soon as I can afford it!!
    Heck!! I'm used to the DA trigger on a Walther P5, so, I might not even mind it!! :evil:

    cheap 3.50 trigger fix

    take apart slide put in bowl of alchohol (trichloethylene if you can get it)
    take out let dry. now dissemble the firing pin (take off plastic stop on end of slide) be careful the extractor spring may fly wild on ya.
    replace with wolff spring 3.5#. dont reassemble yet
    now where sear and slot in slide meet polish that slot. use an emery board. your just smoothing it out reducing some friction there.
    next on the trigger connector do same thing on top of tabs coming off trigger connector.
    now where trigger connector and slide mate. get some steel wool.fine steel wool. polish those surfaces too. remember were reducing friction not removing metal. 1 drop of oil in cam block (end of trigger connector) reassemble unit. dry fire LOTS
    reduced smooth trigger pull
    totally different trigger than the one i bought
    have fun be safe
    remember all guns are LOADED until we know otherwise

    I've fired my pump-you-up Sigma enough times that I don't even notice the trigger pull!!!
    In fact, yesterday, I was sniping empty propane bottles, lain on their sides, shooting at their ends, off a log at about 12 yards!!! ;)
    I was also punching 1 liter soda bottles, filled with dirt, from about 15 yards!! :eek:
    So much for the stock trigger effecting accuracy!!! :D

    Of course, I may have a thing for shooting pistols with a hard trigger pull: P38, PPK/S, P5, Sigma, CZ52, Taurus revolver, etc. :D

    The review I read in Combat Handguns stated that the trigger pull was made intentionally hard for safety. I've read several reviews about this pistol and they were all very good I checked one out but it felt cheap when i handled it though and settled on a Ruger P97.

    it is great to hear a positive thread on the sigma. I myself have loved it from day 1.

    good shooting all!

    I totally agree with JBHaire52. I sent my Sigma 40VE to NHO and had the trigger job done and the over travel taken up. What a WONDERFUL difference. I was almost ready to purchase a Glock 23 when I decided to have the trigger job done on the Sigma. I think the Sigma now does better than the Glock. It's like I got a new pistol. I sure saved myself a LOT of money. I raved about it over at the S&W forum when I got it back.

    The atttached image is a target I shot the day I got it back from NHO (25 rounds at 10 yards). Needless to say I'm REAL happy. The two weeks it took to get it back was well worth it. I have also attached a fillable PDF order form from his site.

    Before I sent it in, I called Tom Novak and spoke with him on the phone. He answered all my questions in a professional manner. The guy was great.

    If you own a Sigma or are considering purchasing one, keep NHO in mind. You'll be glad you did.

    Take care.

    Jim

    I'm not sure why the Sigma is still in production with the advent of the SW99? I've personally never even seen someone with a Sigma.

    I have the 9VE. I did a mod myself to lower the lbs. on the trigger pull. The Sigma has two springs in the rear assembly (not sure of the proper name). I took the larger outter spring and cut about 1/8th of an inch off of it. It feels like a 5 lbs. decrease in the pull. I've fired a few Glocks and my Sigma's pull is smooth and clean, very close to the Glocks.

    I have plenty of good words about the V version Sigmas. I've wanted to get a Smith and Wesson for a while and will likely think hard about the Sigma for my next purchase.

    That is great news. I used to own one but got rid of it because of the trigger.

    It was one of the best $250 hi cap bargains available. If I really concentrated it was very accurate. Mine was utterly reliable. It ended up in a swap for a HP.

    The original post of this thread was the one and only post that JBHaire52 ever made. I have a sneaky suspicion that we have been victims of a drive by advertiser.

    I like that comment denFoote..freaking dealer couldn't give me one real reason why I should twice as much on a glock. I'm concemplating that trigger job, but I'm gonna put a few more hundred thru it before I make my decision.

    I polished the internals and cut about 2 coils off of each of the 2 springs mentioned in an earlier post, and dry fired the crap out of it. Now the trigger is somewhat better than my 5 lb Glock. I am going to get another 40VE to "convert" to 357 sig, because I happened to get one of the last barrels Smith sold in 357 sig and I happen to like that caliber. IMO many people listen to the flaming of the Sigma and don't know how to lessen the trigger pull, thus passing up a great bargain in a "plastic" high cap.

    OK, I just called wolfgunsprings & the guy tells me that they sell stricker springs that will reduce the trigger pull but doesnt reccomend them.

    Whats the deal ???

    Cost me a whopping $7.30 to fix the trigger problem

    I own a post-ban SW9VE and love this weapon. I had no problem with the heavy trigger, though it took some getting used to. I think it made me a better shooter. Several of my friends have put rounds through it and every last one of them complained about the heavy trigger:mad:, so I did some research. I heard many of you mention the WOLFF striker spring #30085, so I went to gunsprings.com and ordered one. Upon installing it (took about 2 minutes), I immediately noticed a HUGE difference in the trigger pull... was about half of what it used to be. Untill blasting about 500 rd. of Winchester 147gr JHPs through it, I was skeptical:scrutiny:. 500 rds and not one light strike, not one jam, and the gun will spread a 3" pattern @ 25 yds. I am one satisfied SW9VE owner:).

    So what was it this time?

    Aliens?

    Meteor?

    Angry spirits?

    What movie plot caused this zombie resurrection?

    For all we know the original poster died four years ago. My theory? He signed up at THR. Posted one thread making the asseveration that Tom Novak is the single greatest human being to walk the earth, then died.
