I sent my M&P back to S&W because it was doubling sometimes tripling. My question is if I take out my blue springs that S&W upgraded in the trigger and install JP springs , will my weapon start doubling again. 

I have JP yellow springs in my 15-22's and never had a problem.
I've been shooting .223 and .556 for a long time.
I understand, now, after seeing it, what it's going to do.
It's been pounded into my head for a lot of years to never alter the inner workings of a firearm.
I don't know, with .22, is'nt there a chance of too light primer strikes with this mod?
Just wondering......

I have talked to several senior members here and they all said that there is still plenty of hammer strike to set of the primer that mod takes away between 25%-35% roughly force from hammer strike so I think it shoud be just fine . And if you ever did have problems its $10 for a JP spring kit that pretty much is serving the same purpose in my eyes.
