PDP Steel Frame Match + Rune Tactical Spring Kit

Anyone have experience installing and running the Rune Tactical spring kit?

I installed the 4lb Striker Spring and Trigger spring - went to shoot a match (yeah dumb not to test it out) and ended up with a single shot pistol. Is it possibly that since I didn’t change the plunger spring yet that is throwing off the cycling? Or should I just swap up to the 6lb or 6.5lb striker springs.

I’ve changed the trigger spring previously in a PDP Poly Pro, but never the striker or plunger springs. How does the various weights affect the cycling? I guess my dumb brain didn’t think that spring would affect the cycle of the slide at all.

I’m also running the ZRTS long stroke guide rod. Ammo was light Power Factor 124gr.
