Hi Power - higher recoil spring weight when changing to lighter hammer spring?

[IMtheNRA]

In an effort to lighten the trigger pull on an Inglis Hi Power, I installed a Wolff 26-lb hammer spring. This seems to have helped, and I'm looking forward to testing the pistol and ignition reliability at the range tomorrow.

I am wondering if I should also have installed a heavier recoil spring to keep from increasing recoil stress on the frame and slide.

I use Winchester white box and my own equivalent reloads, nothing hot or +P, but this feels like a big drop in hammer spring power.

What do you think? Oder the heavy recoil spring or will the standard one suffice?

recoil spring should have nothing to do with hammer spring except in terms of cocking the hammer as the slide returns. seems to me that a weaker recoil spring would be the way to go if anything.

to lighten the trigger I'd resort to polishing...

The hammer spring absorbs quite a bit of the energy which is used to re-cock the hammer as the slide travels back under recoil. Having installed a lighter hammer spring, I am concerned about frame/slide slamming together with more force now. That is why I am wondering if a heavier recoil spring will help by absorbing some of the energy that was previously absorbed by the heavy hammer spring.

If you go below say 26lbs main spring(hammer spring), I would put an 18lbs recoil spring in.

Yes the main spring soaks up a large amount of recoil.

Original Browning specs called for a 26 lb hammer spring. In the mid 1970s FN/Browning started using heavier (32 lb?) hammer springs. One reason I heard was because of hot European ammo.

You will be just fine with a 26 lb. hammer spring and a standard recoil spring.

And yes the 26 lb spring helps the trigger pull. I also remove the mag disconnect. Those two simple changes make a world of difference in trigger pull.

I tried lightening the hammer spring and beefing up the recoil spring to make it easier for my wife to rack the slide, but ended up getting a few light primer strikes and switching back to stock springs. By far the best thing to do to improve BHP trigger is remove the mag disconnect. Polishing surfaces will help as well.
