Shooting major with a Stainless Phoenix Trinity grip...what is the recommended recoil spring #? Main spring #? For USPSA Limited competition being the goal, flatter. Thanks for any and all guidance.

Honestly. its all preference to what the gun/shooter combo likes. I suggest buying a few different springs from your preferred vendor and trying them out. I have a 12# spring in my Edge with a PT grip. Can't remember what the main spring is, maybe the 17#.

I have a CRP 5.0 Eagle from Dawson and it came with a #13 recoil spring. I like it and it works fine.

Below is a link that will help you decide.

The chart is a good starting point but doesn't cover the full range of "what works" with different guns.  For instance, they recommend 9# for Open major, but I know a lot of folks who use 8# (or even 7#) without any problems.  YMMV.
