It’s a keeper! Ran 50 rounds today with the OEM mag spring, the Nordic extension and follower. Shooting consisted of a mixture of Federal Reduced Recoil FC, military buck, suprema 9P buck, and some target loads. It cycled everything perfectly and patterned very well with all the buck, but especially well with the FC. At 25 yards with FC I could cover the spread with my hand.
target is at 12 yards.
