recoil spring on lighter slide

[jimbullet]

Just looking at the logic behind.

 

I have heard and have been following the concept that if I were to lighten the slide, say make it tri top, some lightening cuts/ serrations to reduce reciprocating mass and weight, that given the lighter mass, I now need to reduce the recoil spring weight to make the gun track and return after every shot. 

 

Is it correct to say that the lighter the slide, the recoil spring should be lighter ?

I don't know about 2011s, but there are a couple of guys over at BHSpringSolutions dot com who have put some thought into spring combinations and slide timing. You may want to go over there just for some ideas. They have videos, text, spring kits (for 1911s), etcs.  As I understand things, you have to consider not just the recoil spring, but the main spring and firing pin spring, as well.

Yes, you can install a lighter recoil spring after your slide has been lightened, but the action of the slide on your gun is more complicated than that.

As a basic rule the lighter the slide the lighter the recoil spring. 

 

It works as a system in partnership with hammer spring and firing pin stop plate radius.
