Sigma Trigger Spring Option

[freesoulvw]

I have posted a few posts on the forum and I have yet to even pick my sigma up from the FFL dealer. I still let my mind work and spend a little time on the net looking up stuff to see what others are doing.

So my question is this:

Instead of cutting a spring in the trigger assembly/removing springs(by following the "rules") would it be possible to use heat to an advantage in our quest for trigger nirvana?

The reason I ask is that when I go to make say, gas tanks or pannels for hotrods or bikes,ect. We use heat to anneal/temper the metals making them softer thus eaiser to work. I was thinking if it would be the same thing with a spring. Taking some heat to it would change the molecular structure changing the spring weight. I have a super small accurate spring tester that is used for checking spring weights/tolerances for minature springs, maybe I will take apart some bic pens and throw them in the oven or under a torch to see what changes might develop.

I am not one that usually experiments with his own stuff so I dont even plan on doing the "simple" trigger mod on my sigma when I get it, the topics that I post are more a way for me to throw my ideas out in the ring to see if anyone else out there might see them and get his/her brain working and maybe just might find a different way to work the same problem.
Any comments or concerns please post to hear what others think. I am not a scientist so any experiment would be trial and error. There might be smarter folks out there that have formulas for metalurgy, that could work out type of metal+range of heat+time of heat applied=amount of tension removed from said spring....or I could be just talking out of my ***** later guys, have fun

Why would you buy a new gun with the intention of taking it apart and modifying the factory-installed springs in it? If you know the trigger is going to be a problem for you when you get the gun, why not just find a different model that is more to your liking?

I wouldn't say I buy things for the soul purpose of taking them apart to improve them, but then again, what's wrong with doing it? We all add custom accessories to our toys. Every toy I own is different from the OEM model I originally bought. From my truck to my boat to my fishing rods and reels to my guns. To me, tinkering with my toys is a hobby that most guys can relate to. As I tell customers on a new yacht delivery, Every boat is a compromise unless you spend the extra $$ to have it built to your exact specs. I as a regular ol' working man, don't have that luxury, so I buy what I can and customize/improve it from there. To me it's my version of therapy. Plus, I've never been a big fan of having the exact same thing as everyone else. Just my $.02.

The difference is, at it relates to handguns, there are hundreds of other affordable choices out there to choose from. Furthermore, if this is going to be used as a defensive handgun rather than just a range plinker, why take on the unnecessary liability of modifying the factory trigger group components?

Taking some heat to it would change the molecular structure changing the spring weight.

Let's keep this simple.
1. Hardening and tempering springs is difficult to impossible without a high-temp oven to accurately control heat.
2. S&W has stopped selling the sear springs separately, so you are looking at having a new compete sear assembly factory installed when you ruin your springs.
3. The "trigger spring" is a dinky little return spring that has almost no effect on trigger pull, so fooling with it is pointless.

To the OP,,,

Do as you want with your Sigma. And more power to you. The Sigma is a fantastic $200 pistol. Any thing over $300 and you got burned. It's kind of like being in Mid-Fi hell in the audio world.

The sear by design has a feeling,,, maybe seen as limitations by some of flat out faults and flaws. It does not break clean, feels like it's hooked to sponges and rubbers bands at best. But get this!!! It will work without a spring one in the sear. I've done it. I've never owned a bottom feeder I could make bang with, and no springs in the sear,, or busted springs for that matter. Fire it,,, flip the trigger back forward, and pull again. That in and of it's self is a feat of near biblical means. LOLOLOLOL. And possible because of the design.

Tweak on... S&W may not understand. Members here may not understand. I can share with you S&W left something on the table for us to play with.

I've been playing with trigger pull length and take up on mine. There is room for improvement there also. Timing is in the nubs on the trigger transfer bar. The slop in the trigger bar at the sear pin does play a great roll in reset and keeps the shooter from getting there finger slapped.

I truly wish I had the time to work on some parts for the Sigma. S&W left some stuff on the table worth improving. IMHO

I honestly believe they did not push it's over all development because it would have come close to the M&P. IE segment compression which sucks from a marketing stand point. Just ask GM, Ford, Honda, Nissian and Yota.... LMFAO

well I see that a simple option threw someones pants in a wad.....well I wrote that before I even felt a sigma trigger pull, and I should have worded it different, you are right if you push down on the lever that connects the trigger mech to the back of the guns "workings" the trigger is as smooth as can be. its only when you just pull the trigger and let it do its thing that you can feel a the gritty ridges that almost stop my triggers travel before it even hits the breaking point. the post I posted was just as I said a thought about a different way of doing things. I personally dont know anything about the internals of gun mech(dosnt mean I am not a learner)I will end up learning how things work, but I also feel that everyone has the option of improving upon anything they see fit, I respect the fact that someone wants to leave things alone, but without the tinkerers of the world where would we be right now, certainly not reading this computer screen. In future I will prob leave my "modification" posts out of the forum as it seems to evoke the opposite of what I was going for, instead of getting wheels turning I got doors slamming.

I will end by saying that now that I actually have my sigma, the trigger weight is not an issue for me at all, it is just fine, I was more concerned about the grittyness I am feeling, and now that I know that the reason for the grittyness has nothing to do with springs that leaves this post moot- good day
