Well I got the spring, but not with the guide rod. Gonna have to get my gunny to switch out the springs. The new spring is about 2 coils longer than the old one. Guess the first one has worked its way shorter. May explain why it doesn't apply enough force to reclose after a pinch check. I'll try that factory spring for a while, but I guess I have to start counting rounds again. If this factory spring only lasts 1500 rounds like the original, then I'll probably go to the heavier Wolff spring.
