I'm going to put a tungsten guide rod in my Gen 3 G34 and I like captured springs. I understand the basic recipe for tuning a gun but I'm not sure which spring weight is best to go with. Right now I'm shooting 132-ish PF loads because I don't want different loads for different games. I can tweak the load a bit. So, 13 or 15 pound spring?
