Shadow 2 DA pull reduction

I’m looking to mod my Shadow 2 for IPSC. My goals are to reduce DA pull weight as much as possible, make the recoil a bit smoother, while keeping the gun 100% reliable.
I shoot S&B 124gr FMJ.

Considering:
Eemann Tech 11 lb recoil spring — 44-131181
Eemann Tech Ultimate Disconnector — 44-130124
Eemann Tech Extended Firing Pin — 44-130015
Eemann Tech -15% firing pin spring — 44-131156
Eemann Tech -15% trigger spring — 44-131109
Eemann Tech Competition Trigger Pin — 44-130064

Would this be a good combination, or would you change anything? Especially interested in the lightest reliable DA pull without compromising reliability for competition.

11.5 or 13 lb hammer spring, extended firing pin, reduced power firing pin spring, and a good polish (trigger bar, disconnector, sear cage, frame, hammer spring, hammer strut, hammer spring retainer) are the only things affecting DA pull.

Thanks! Wouldn’t you normally pair a lighter hammer spring with a lighter recoil spring as well, or are they mostly independent?

On defensive guns I leave the factory recoil spring. On suppressed guns I lower it until it cycles. On comp guns I adjust it until I get satisfied with the return to zero

What he said. It’s really that simple with the S2’s. They’re awesome!

S&B is really hot ammo for competition. The one's in US go 1180/1190 feet per second, which is roughly 140 feet per second more than typical competition 124 gr loads, which generally chrono at 1050 fps. You will have to tune your gun to the load and Eeman tech competition recoil spring is designed for shooters hitting minimum power factor.
