Just thought I would let you guys know. My ccw is a XD45c. It has the captured spring from the factory. I shoot it once or twice a year in IDPA with full loads, just to stay familiar with it. I normally shoot an XD or XDm, so the gun is always familiar. I want to start shooting it in the new IDPA CCP div. The div allows any caliber 9mm & up with a min 125PF, 8+1, bbl less than 4.10". So I wanted to see if the stock dual spring would indeed run a minor load & it will! A 185gr bullet @ 700fps runs the gun perfectly w/o a spring change. So while not a 9mm, still soft enough to be competitive & it gives me more trigger time with my ccw. BTW, POI was not really affected. I can easily put the entire mag into the center of the head zone @ the max 10yrd limit.
