I have installed many sights using a vise with soft Jaws and a brass punch. It's not fun. This sight installer is 10 faster. I cant describe how much easier this makes it. It takes out all the human error and possibility for mistakes. I was honestly surprised at how robust the construction is. It's not some cheap plastic junk. I have seen other companies sell this identical product for 4 times the price. If your looking for something to make your life easier take a chance on it you won't be sorry.
