Hi.

I want to lighten the trigger pull of my SR1911. I don't want to do any polishing job. Just swap out the mainspring spring & the firing spring. What is the best combination of that two springs to lighten the trigger pull.
 
Good luck with that, mainspring has nothing to do with it, if you are taking about the slide spring, the hammer spring will.
 
I personally don't believe it's worth the effort to achieve your goal OP. When you reduce the strength of the hammer spring, it reduces the impact of the hammer on the firing pin and could lead to inconsistent ignition.

I fully understand, factory 1911 triggers are atrocious at best these days. There was a time when you could order your pistol from the factory with the desired pull weight. The sear mechanism and triggers on 1911 don't lend themselves to light pulls.

I'm not going to try to dissuade you from your effort but IMHO, when push comes to shove, you will resort to stoning the mating surfaces to a point where they are still safe but have less travel and creep, with crisp, clean disconnects.
 
Cheaper, easier, safer and you get a more satisfying end result that will last longer if you simply have the gun's trigger 'smithed by a pro. It isn't the springs that are bad, there's a ton of geometry in there, and mating surfaces that have to be done right. Trust me on this.
 
About all you can replace spring wise without doing any major polishing is the hammer spring. 23 lbs is factor maybe try a 20 lb. That will help a bit ,if you feel sporting you can give your center leaf spring a slight bend back to lower the disconnector pressure but that's dicey because you could cause other issues. It's all really a package deal, 1 thing won't be a huge reduction. The you may get a half pound reduction and still be fine with the above ideas.

My 2 cents.
 
Just but a new hammer and matching sear from Brownells or maybe even Dlask Arms.
Probably would still be cheaper to send to a smith though.
I do all my triggers on every firearm I have. I find it fun but I guarantee you will screw some up before you get good at it.
I only do my own triggers and won’t work on anyone else’s. It’s very rewarding to just polish surfaces and get a trigger pull that’s quite a bit better but still safe.If you go this route get a good trigger pull gauge and watch lots of videos and take your time

My SR1911 had a very crisp trigger with negligible creep and overtravel when new. Guessing it was about 5lbs when new. Tiny bit lighter now after a couple hundred rounds.

JMO, leave your trigger stock for now. Break in your pistol with a thousand rounds. You’ll be surprised with the much lighter trigger
after the break in. Your trigger finger will also be broken in by then.
 
Gun smiths make a living fixing "gunsmithed" guns, thought you can't go wrong with spring changes.
If it was a Norinco, I would say have at it, this one, the above posts are good advice.
 
If you want to stay under $50 get a light or competition sear spring and a replacement main spring and just cut one coil off of it at a time till you get it where you want. Also a trigger with over travel screw is nice for a cleaner triggerpull .
 
Back to the original question. I dropped the main spring (hammer spring) to a wolf 19 pound and the recoil spring to 15 pound. Shoot lighter reloads and federal primers.
 
X2 do not modify trigger until at least a 1000 rounds. What works good on a new gun isn’t going to work on a used gun.

I’ve seen twice now where a trigger was adjusted on a new rifle only to have issues after it had worn in.
 
Polishing and stone can achieve what you want, but since you shut that door down, just shoot it till the sear matches the hammer.

I am against running anything lower than 19# MS as well. I bought all the tools and books to do a 1911 hammer job, and with a 19# spring, its a 3.75lb trigger with proper hook height and sear angle. I drop in a 16lb MS and a 4 leg sear spring, instant sub 2lb trigger, but scary light 2lb.

Shoot till you are comfortable with the gun then go from there. For some people, having a SA trigger like a 1911 can boggle their mind as their mentality is safety first. Shoot more and you will discover that the 1911 is very safe as long as you do all your manual of arms properly.
