Power Plus Mags are designed to significantly increase reliability and service life even when kept fully-loaded for extended periods of time. This level of performance is made possible by holding tolerances 75% tighter than magazines made to military specifications and by using extra-stiff coils of aerospace grade wire that produce more power than other magazines. The base pad is removable for convenient cleaning and maintenance. Power Mag Plus magazines have a steel follower that run smoother and resist wear.
