I was just at Glockmiester shopping for some G30 stuff. Im getting a modified carry trigger, new 10 round mag with the Pearce extender installed and a stainless captured guide rod. I already have Meprolights. I looked and looked for a 20# recoil spring for my 30. I could not find one at Glockmiester. Am I just missing them or do I need to get a Wolff recoil spring. Will a Wolff spring fit the Glockmiester guide rod. I noticed on Wolffs website, they note that thier springs are to be used with thier guide rod. Wolff doesnt make a captured guide rod though.
