The Real Avid 4-in-1 Tool for GlockA(R) is sleek, ergonomic, and packed with function-in every way a thoroughly modern armorer's tool for GlockA(R) owners. Four different tools store inside the handle and each snaps open and locks in place with the push of a button. Remove pins for disassembly, change out front sights, remove slide lock spring and locking block and adjust aftermarket rear sights. Mfg: Real Avid
