What a trigger pull!!!

[rnrnrn]

I purchased a Sigma 40 few weeks ago great price rebate plus 2 free mags. I have shot the SW MP40 and thought the Sigma40 might be similar...boy was I wrong.

First time shooting it I couldn't hit the side of a barn. The trigger is long and tight. While at the range I shot a Glock, Sig, and the SW MP40,,, no comparison. All three guns out shot the Sigma. I guess it just takes time getting use to the trigger pull or a stronger finger.

I contacted Smith & Wesson regarding the trigger. Pull is apprx. 11pds. I thought maybe they could change out the spring. No can do. Also contacted few gun dealers in my area Palmdale, CA. The trigger is (what it is) can not change.

Guys lets face it the Sigmas are JUNK . I own three S&Ws and I am not downing the company. But the Sigmas are like a bad science experiment. Every one that I have laid hands on shot like a$$ and the trigger pull was unacceptably funky. Working at a gun range I shoot alot of different guns and I have to say that aside from the guns that are so cheap no one trusts them (you know the brands), this is the worst shooting gun I have seen. The M&Ps are far superior weapons. Its hard to believe they are from the same manufacture.

after my first trip to the range with my sigma 9mm my finger had almost a blister on it from the trigger. all i can say about that is 500 rounds later it is a dream to shoot. i guess you gotta get the rounds through it.

I changed my striker spring. I have the SW40GVE. Wolff Gunsprings Manufactures springs for modern and vintage firearms, guns, hammer, pistols, handguns, revolvers, rifles, shotguns, semiautomatic, accessories, weapons, law enforcement, hunting, shooting, recoil, colt, mainsprings, magazines, IPSC The instructions to change the spring are at midway.MidwayUSA - Wolff Striker Spring S&W Sigma 3-1/2 lb Reduced
I replaced mine so I could sell it. I changed my mind. Now I have two sold with the spring kit. If you decide to sell yours rnrnrn how close are you to Eastman GA and how much do you want for it.

It isn't oil that manufacturers use, it's a rust preventative. As they have no idea as to just how long a firearm may sit on a shelf. So they coat it with a rust preventative/inhibitor. So it's always a good habit to get into to always first clean any new, or even used firearm before your first time shooting it/them.

Also, doing so helps you become somewhat familiar with the firearm. I'd also say give it at least 300-500 rounds and see how it feels then. Some firearms do take a bit of use. Make sure to use a good high end brand of ammunition also. Using some cheap dirty ammo isn't going to help it any that's for sure, MHO anyhow. They tend to fire and work a bit better after some good use. Then there are those that no matter what you do, or don't do or how much you shoot through them, or what kind, nothing makes a bit of difference.

I hope for your sake you get one that after some use, with good ammo, works to your liking. If not, contact S&W and explain to them and see if there's anything they'll do.

Worse comes to worse, give this a try.
MidwayUSA - Wolff Striker Spring S&W Sigma 3-1/2 lb Reduced Power $6.49. Sounds like a cheap fix to me?

Also found this on it. Don't waste your time on the link, it didn't work for me. Well it worked, it just didn't take to to where the person who left it meant it to. lol

So it sounds as if this trigger thing is nothing new, yet it can be fixed and when it is, it's a whole new gun... Good luck and be sure to let us know if it gets better over time and use, or if you tried/got the new spring or had a gunsmith do his/her thing to it. Or if you just said screw it and got rid of it.

Oh yeah it takes maybe ten minutes to replace the striker spring. When you take the plate off the back plate off remember the extractor spring is under there go slow and point the back at a towel or something so you can catch the spring when it comes out.

If it were me and mine, it'd be the first thing I'd do or try that's for sure. And to get it down to, what did it say, a 3½# trigger pull, YEAH BUDDY! lol

[jimkim]

If you follow my link to Wolff springs the spring is $3.49 there. I just posted the midway link so you could read the directions. GM is right Yeah Buddy! Mine is a tack driver now.

Dose changing the striker spring reduce trigger pull from 11 lb to 3.5 lb or just reduce it from 11lb to 7.5lb. Also dose this change the amount of travel the trigger has.I have not shot my 9ve for a while and today I took it to the range. Right now I am not very happy with it.Thanks for any help anyone can offer.

[TexasT]

I thought I read it is reduced from 11 to 8 or so. I'm going to get it changed tomorrow. I'll let you know how it goes.

i have replaced springs with WOLFF springs in a number of my firearms.
i havent done it to the weapon in question BUT i have had some good guns with terrible trigger pulls (the ruger sp-101 comes to mind) that are a joy to shoot now.
that ruger went from 15 POUNDS! to a sane 8

[jack007]

thanks for the info yall and let me know how it works out.

Guys! Please remember that when you reduce the power of the striker spring the striker hits the primer with less force. There is a reason that S&W put that particular weight spring in the gun, to make it reliable. Never reduce the weight of the striker spring in a gun that you may one day save your life! I have reduced power springs on my competition gun (G34) and the trigger is nice about 2.5 lbs because those cardboard cut outs wont kill me, but my carry and home protection guns are stock. Ive been around some and haven't seen a Sigma in IPSC Limited Class.

good point!
i have usually gotten the kits that have a series of graduated weghts
for example with the ruger kit they come in 8-10-12 lbs.
with this gun i started low and got reliable ignition @8lbs.
no light strikes in about 300 rounds.

It just concerns me when I hear of someone lightening a striker spring and me not knowing if this is a "Lets go to the range and have fun" gun or a "If my life is in danger and I will resolve the situation with this" gun. I wont put my life on a tricked out race gun. It may be fast , but you must remember the balance between speed and reliability. My SHTF gun is a STOCK G17.

Thanks for the info 502. I was concerned about that very thing.I use a Beretta for things such as protection. I just thought the S&W would be fun. Got what I paid for.But it always fires if you can pull the trigger.

I'm not familiar with the pistol. If it's a SA/DA then I would get a few hundred rounds through it. If it doesn't lighten up then return it to Smith & Wesson.if you have a warranty on the pistol. Complain that the trigger pull is the worst POS that you have ever encountered, they'll probably put it through the pro shop. If no warranty, I'd still call Smith and see what they will do for you. I would imagine that if you make enough noise, they will take care of the problem. If not tell them you're going to post on every forum and web site,you can find that they (S&W) won't stand behind they're products and since they are Walther USA too, the same must be true. If you still don't get any satisfaction, then get a spring kit. Having been a S&W armorer for over 30 yrs (Never took the plastic gun class) I only had trouble with Lanier when they owned the company. The DA trigger probably is supposed to be between 12 and 18 lbs from the factory if its a DA/SA if not I would imagine that a 8 to 10 lb. pull would not be unreasonable. The final thing would be to take it to a gunsmith. Remember the pistol was designed for Military and Police, it won't have a "nice" trigger pull.

I was going to buy a Sigma myself in 9MM. I wanted a lower dollar 9MM just to practice with. I rented a Sigma first and glad I did. That trigger pull was so long I could have used it fo crack walnuts. So heavy it felt like I was at the gym. Good example and proof that you get what you pay for.
