GTUL has developed an integrated system to disassemble and clean the Glock magazines. For use by Law Enforcement, competitive shooters and all those who demand positive ammunition feeding. This system addresses an often overlooked area of firearm maintenance for your Glock, cleaning the magazines. You can now take apart your magazines without marring, gouging, or damaging the metal liner. Quickly remove dirt, dust, powder residue and grime that may hinder reliability and cause a failure to feed. This GTUL tool works with all 10MM and .45ACP Glock magazines.
