460 Rowland® Glock 21 Magazine Shim Set


Our 460 Rowland® Glock 21 Magazine Shims enable full engagement of your mag release lever preventing damage to the ledge of your plastic Glock Magazine.
This damage may lead to your magazine dropping out of the magazine well when you fire.
The Set of two shims is easy to install: Just press them in place as indicated in the photo and the aggressive adhesive backing will finish the job.
  • Install the Shorter, Wider Shim on the Left Side of your magazine
  • Install the Slimmer, Longer Shim on the Rear Face of your magazine
Use one set of two shims per magazine.
