M & P Limited gun question

[RWF]

I hope this is the right place to ask this.

i am working on a M & P Pro Limited/3 gun pistol. Dan B has done the trigger (2.7) and texturing and right now the slide is at springer for slanted slots for some weight lost and looks. I plan to use loaded ammo from Armor and Atlanta 147 grain at about 880 pfs is what they claim.

So where should i start in looking for a recoil spring weight?

i am thinking 13#

Thanks.

Yes, the pf should get you about 13#, but you may have to consider 11#. Be sure the brass gets kicked 3-6 feet or you need a weaker spring.
