sig p226 main spring question

[alantani]

has anyone replaced a main spring in any of the newer sigs? the double action pull is 10 pounds and the single is 4.4 pounds. i'd like to lighten it up a little. i've been practicing with the laser in the house, trying to keep the laser from jumping all over when i squeeze the trigger. i'm getting better all the time, but i lightened up the main spring in the walther and it helped tremendously.

You can change out the mainspring for a lighter one but I would leave the sear spring stock. You can further reduce the trigger pull and smooth it out by polishing the various fire control parts. If you are planning on using the pistol of defensive purposes make sure you know what you are doing because if you lighter the mainspring to much you might start getting light hits/misfires.

i'm just punching holes in paper. i started looking at this more and realized it's just the main spring and not the sear that i would change. the stock spring is 24 pounds. i was thinking of dropping to 20 pounds. the mainspring seat is the type that is made of plastic. it looks like it is easy to change out.

I bought the e2 grip kit and bought the updated spring and changed it out myself. Very easy, just did it last week. And it does help with the trigger pull, but even I was used to the old one. The new spring/seat is a big improvement on grips and somewhat noticeable on the trigger.

+1 you beat me to it...

I'm assuming from the look of your internals that you have a new-style P226 with a machined slide. If you have a folded slide then I am pointing to the wrong parts.

You can find the correct spring here. You might find this tool useful to remove the spring base without scratching it up. You want the little notched screwdriver part.

Factory stock is 21lbs. Anything less then 19lbs is not recommended unless you are making your own ammo and you know you are using only softer primers.

If you want to change all your springs use this kit for a nice pull. If you make your own ammo and know you are using soft primers you can use this kit for an even lighter pull. Be aware that the Competition Action Upgrade Kit will not fire a large percentage of factory ammo as the mainspring is too light (17lbs).

Don't use the gun for HD after you make the trigger too light as it probably won't fire the hard primers used in HD ammo reliably.

Personally I just stick with stock spring weights. It makes it easier to switch between guns if I do this because if I start messing with spring weights I'll need to change them on all my Sigs.

After some practice it gets really easy to keep the sights from moving during the DA pull, you just have to put the palm of your hand in the right spot on the back of the gun.

Depending on the spring you put in, you can change the pull weights. However, let me caution you on the negatives of doing so. Lowering the spring weight, while reducing the trigger pull weight, also reduces the force the hammer falls to strike the firing pin which ignites the primer. Too low and you can experience irregular ignition of primers and failures to fire. If your weapon is used strictly for range or target use and you don't mind the occasional FTF, then lowering your spring weight will help the trigger. This can also restrict the ammunition you use because of primer hardness. Most who go to lower spring weights, test their weapon extensively to find the best spring weight and ammunition for reliable ignition.

If your weapon is to be used for carry and/or self defense, I strongly advise AGAINST using anything other than factory springs for your particular weapon. Sigs are designed and tested using factory components that will operate the weapon reliably when properly maintained and serviced at specified intervals.

haha thanks budd, I did notice a difference when I changed out the old one for new one. And the new grips are sweet.

I agree, I dont recommend changing weights or anything from stock. The new spring upgrade is most certainly easier to change grips with though.

OP Where are you located?

If you want to improve your trigger, I can without modifying springs and keeping it carry safe.

+1. It's always nice to have a Armorer around.

Eh I just ordered my SRT and get it this week, trying to figure out if it's even worth putting in considering I don't ride the reset. That and it looks alot harder than the mainspring change out.
