Really like this product. Happy with everything but the installation. The hole is easy enough to drill, but the actual site is a very tight fit and required either a vice with pads to gently push the site in place or manually filing the side down a little at a time until if fit properly. The direction are not overly clear but thanks to others who purchased this product there are enough videos and comments from people to help you instal this properly. Install time half hour to a hour once you gather the proper tools. After installation we test it at the gun range and the site was spot on. Very pleased with this product and I highly recommend it.
Pros: Great product, improves aiming at target
Cons: Takes time to install
