S&W Sigma Trigger Troubles


milkmood

Dodge this.
I have a couple of problems that may be related. The first and most important problem is that I can't hit an 18" target from 5 yards :mad::mad::mad:

But thankfully, I think that's related to a sticky trigger. When I squeeze the trigger, not only is it a heavy trigger and a long trigger (those I can live with), but it seems to be sticky, like I'm not lubing in the right spots or something. It's like there's plastic rubbing on plastic somewhere. I realize this is a cheap gun, but has anybody else experienced this and found a fix for it short of replacing the entire trigger mechanism with some aftermarket outfit?

I for one am not impressed with sigma triggers.
 
Best thing to do would be to have a competent gunsmith re-work the trigger. You could check Brownell's to see if they sell an aftermarket trigger for the gun as well.

My ultimate suggestion would be to ditch the Sigma and get a better quality firearm. If you want to stick with S&W, there's the M&P. Otherwise there are a lot of other options out there.

Good luck!

Yeah, I was eyeballing a Taurus PT145 yesterday... big bullets, higher mag capacity than a 1911, compact frame...great price. Trigger is way different. I'd also consider an M&P 45. I'm sure the bottom line is...you get what you pay for, as with anything in life.

The Sigma might make a good backup.

Amen on the M&P45 I love mine. I did the rework on the trigger myself for here in MA they come with a trigger pull of 10+ lbs. I now have it at 6lbs and it works for me.

They are worth the money...

I read too many negative things about the Sigma to even be bothered.

Peace.
 
I spent a couple hours at the Ben Avery range today, and about 250 rounds through it, figured out I can adapt to the friction in the long draw of the trigger. If I draw half way, until it's a hair trigger, then take my aim...I can hit the target just fine, very consistently, 10 yards into 8" circle, and out to 15 yards within 12" circle...so even though I'm not terribly impressed with the trigger still...I now have a usable gun the I feel more comfortable with.

I'm still thinking about trading it up to a Taurus PT145. Nice little pistol...10+1 in a compact .45 seems like a plan to me, and the price is right! :pleasantry:
 
If its a new gun, try using a dry-fire dummy round (as in Snap Cap) to protect the firing pin, then drive your wife crazy with about 500 to 600 dry snaps. This usually smoothes out a new trigger. Then consider a trigger job. This worked for me with a new Kimber and a Ruger SP101; besides ending up with great trigger control, you get a "Popeye" trigger finger!
 
I have three sigmas and have posted the following advise on many other sites.....

Wolf Spring out of newtown square, pa. offers a lighter weight striker spring. this installed part will lighten the trigger from about 10 lbs to approx. 7 lbs. It will make a difference in the smooth operation of the pull as well as an overall improvement in accuaracy. I am not sure that practice dry firing will lighten the factory trigger to a large extent and in fact the practice may not lighten it at all but make your trigger finger become accustomed to the 10 lb pull. Yes matelp the popeye finger.

Furthermore, the new spring may deliver more consistent dependability as opposed to adjusting, cutting or tampering with the existing spring. A lighter trigger pull and an increase in the price may diminish the endless bashing of this firearm. Even with the heavy pull, there are many happy owners of this firearm. Smith and Wesson is a reputable company and if this gun had large numbers of serious problems, S&W would pull it from the market all together or revise the mechanics which they have done already with the updated version. Taurus revised the Mil Pro three times after the disasters of the first generation having problems with cracked frames in the 45ACP model. If only they could improve their service department and bring that facet of their business to the same level of smith and wesson. I have been fortunate, my three taurus firearms have not been in need of factory service.

I replaced my Sigma striker spring with a Wolf spring. It reduced the trigger pull but also failed to set off hard primers 100%.

Sorry to hear about the problems. I have not experienced any such problem. What brands of ammo have the hard primers? I will certainly give those cartridges a try and see if my firearm acts in like fashion.

The S&W Sigma is truly a quality gun at a Super price. I am however surprised by the variance in trigger-pull from gun to gun. (Next time you go to your gun store, have them pull out 5 Sigma’s and compare the trigger pulls. 1 of 5 is “not too bad”…… Most are heavy spring and almost a “grind” in the break. The good ones will still feel a little heavy but break clean. (Unlike most other guns under $300.00, the Sigma, good trigger or not, will still fire every time when you pull the trigger.) Some are just harder than others and need and adjustment.
That grinding- rubbing feel is most noticeable in some guns when it’s not even cocked. When you pull the trigger, you can see the pressure on the guide with the slide is removed. You can make it smoother and stop the binding by adding oil and compressing the springs in the striker retaining group. This can be done from the top using a pen. Just keep pushing down and then hold. THEN PULL THE TRIGGER until it stops hanging up and gets smoother…. (I think the double spring system binds against each other.)

If that doesn’t work, this is another option:

I hope this helps….

Oh – I also have an original Sigma 40, the one Glock sued S&W for, and the trigger on that one feels just like my Glock. Very light springs and smooth break which is around around 5lbs. Did S&W changed the trigger…….??
 
If you cannot do it yourself have the trigger job done, it will make a ton of differance in trigger pull, a bud at work had one we all shot it at the range some time back, about 5 or 6 people shot it, and it is not a new gun, well broken in, but the funny thing is the newbys that were with us did not seem to see a problem with it untill they ran a few rds thru something else, compared to the Sigma, the Glock trigger feels like butter
 
Yeah - It's hard to beat a Glock!! The Sigma with a good trigger is a very comfortable - cost effective option.... :pleasantry:

I would rather have a inexpensive S&W (Sigma) with a trigger job then anything Taurus makes.
Taurus are range pistols. They work great for plinking. If they FTF, or break, what does it mater at the range?
How many law enforcement, security, or military use the Taurus brand?
If your life is going to depend on a firearm, buy a quality one.
Sorry if I hijacked the thread.
Good luck with your sigma.
 
Ive had both sig's.The 40 cal that glock sued was a kick ass gun!!!! I could slam 4 15 round clips through it as fast as i could and it wouldnt miss a lick. I loved the triger on it never no problems. someone liked it beter than me and stole my gun,car, and everything my in it. Well as crazy as it sounds I went and bought a new sig. WOW... i thought i was going to have to use 2 fingers to pull the triger. but knowing the **** you can do to this pistol... im loving it. now my gun is like my watch, its a part of wakeing up..
 
dont mess up yer sig.

if you cant do the Trigger Tricks, dont mess up yer gun, take it to someone who can....????? does anyone know if you can get internal sights for the sigma. if knot its time for one...
