The SureFeed Magazine Follower Spring for the Ruger MKIII and MK IV is 25% stronger than the factory spring. The increased spring rate improves feeding in all Ruger MKIII and MK IV magazines. The SureFeed Magazine Follower Spring will eliminate feeding issues caused by the round either being stuck or slow to feed from the magazine. This happens during both slow and rapid fire.

Take a look at Volquartsens and see there's no comparison between the factory spring on the left and the SureFeed Magazine Follower Spring on the right.
