This tool is great to have in your gun bag or coat pocket for those last minute adjustments because of weather conditions or whatever. It has always come in handy, and it has other uses too if you use your imagination or are in a tough spot.
Pros: Easy to carry, easy to use, has specific tools for Ruger models
Cons: No carrying sheath
