I'm not overly impressed with this Performance Center trigger pull, the single action pull is fine, and I can live with it. Now the double action needs help, thinking of installing a Wilson Combat spring kit. I've been inside a few revolvers so no issues there, and the price is like $20 but asking if anyone has been down this road?

Any advice appreciated.

My Lyman trigger guage goes up to 11.lbs and wouldn’t read the double action pull on mine. Local gunsmith got it down to 7.lbs but I had to switch to Federal primers from CCI to get it to go bang every time.
 
I have a Wheeler trigger gauge and tested my TRR8 and R8. Along with two Super Ruger Redhawks because I had it out.

Interestingly enough, both the TRR8 and R8 have a 9 lb 11oz average pull which the 44 mag SRH also has.

The Toklat (454 Casull) is one pound heavier. Which isn't surprising because you can feel the extra weight when shooting at the range. I thought the difference would have been more.
 
I haven't tried the Wilson kit, but I have used Wolff springs in K and L frames.

I don't like trigger rebound springs below 15 lbs (stock is generally 18 lbs), because the reset starts to get mushy, but a lot of that is personal preference. That was enough in my 64-7 to drop the DA pull from an almost maxing out my trigger gauge at 11.9 lbs to 9.4 lbs, and the SA from 4.5 lbs to 2.8 lbs. However, some of this may have been break-in and cleaning/oiling in what was likely a lightly used security/armored car company gun that I got on Gunbroker.

I have Wolff's "standard" Power Rib mainspring in a 686, but had light DA strikes, especially with harder and Magnum primers. I had to get an extended Apex firing pin and fit an extended strain screw for reliable ignition with hard primers. I filed the strain screw until I got the pull to 8.5 lbs, and now if it doesn't go bang DA, it's probably a bad primer that won't go bang on SA either.
 
If its a new revolver, you gotta give it at least 900 rounds to smooth out. And for the performance center Wolff type mainspring to loosen up.
It may actually loosen up to not make igniting Cci primers reliable.

From weakest to strongest mainspring, its the performance center/ wolf spring, then the wilson combat spring. And the hardest is the stock mainspring.

I have CCI, Federal & Winchester primers on my reloading bench. Haven't built a standard carry load yet. I'll run some ammo thru mine with all the factory springs and see if it slicks up any

Springs are only half of the "good trigger" equation. S&W mim parts are generally far smoother than their predecessors and seldom need polishing, but the frame is still machined and thus subject to causing drag. Polishing is a must, but if you've never done it before, read up on the process.

I tried the Wilson kit in my new 627 last fall. While it did lighten the pull I wasn’t very happy with the overall result. I ended up sending the gun to Nelson Ford for an action job as well as adding an apex hammer.
 
I'm in the shoot it 1000 times before messing with it camp.

I changed rebound spring on a new 686.
SA trigger was excellent. Until The parts mated naturally.
Then it was too light. Scary touchy.

I went back to the OEM spring.
Excellent again.

I have a new 617 with 400 rounds through it.
I'll give it a few hundred more before changing anything.
