The Real Avidz 4-in-1 GLOCK Tool for Pistols is small enough to fit in your pocket, yet big enough to contain the tools you need to disassemble and maintain any GLOCK pistol. The compact, ergonomic design has 4 different tools that store inside the handle, and each tool snaps open and locks in place with the push of a button. Use the Real Avid 4-in-1 Tool to remove pins, change out front sights, remove the slide lock spring and locking block, and adjust aftermarket rear sights.
