Every Glock owner should have several of these simple disassembly tools. The black polymer handle and steel tip combine to form a comfortable pin punch, allowing easy disassembly of any Glock all the way down to the locking block.
Pick up a few and keep one in the range bag, one in the glove box and one on the tool bench. You'll find yourself reaching for one whenever it's time to clean or maintain your Glock pistol. Fits all Glocks. Price is $6.50.
