Looking to purchase a sight tool and am looking for input from those of you that have / use them. I am very anal about my tools, I am a sucker for a well built solid tool but hate gimmicks. I have seen videos of the Uni-Tool which seems to be a "fit all" tool and am not sure of its true quality. Have seen a few dedicated glock tools but in the videos they seem to not set square on the slides and ride funny on the sights themselves (maybe due to poor setup??) I am looking for a first rate tool (dedicated glock or universal as long as it works well and doesnt damage slides, etc) Recommendations??
