The 2011 followers are designed to maximize capacity and reliability in all types of 2011 magazines. They have been successfully tested in both 38 and 40 caliber magazines, from STI, SVI, BUL, Para, Rescomp and others. These followers are precision CNC machined from “Delrin”, which ensures smooth, reliable feeding in the magazine tubes.
The undercut and looped attachment to the DAA mag springs, means a firm hold onto the 2011 DAA springs. You will definately feel the difference.
These followers are not designed to activate your slide stop. They are best used in pistols in which the slide stop has been deactivated. This is most common with serious IPSC shooters and gunsmiths.
The DAA 2011 Followers are best used with DAA 2011 mag springs, but can also be used with Grams or TTI springs. Other springs may require some custom fitting or may not be used at all with this follower.
These Followers can be used in shorter 9mm mags as well (with spacer) by shortening 1.5-2.0mm off the back end.
