What new skill would that be and using what type of sight? My eyesight basically sucks and I'm in my 70s so it's not likely to get better. The laser is great for up close, defensive distances and is very easy and quick to learn. I can't see using these sights as laborious, especially if the shooter has some years of shooting behind them. Red and green dot sights have been around for quite some time.Expect to spend time learning a new skill, depending on eye sight (age?) it will make a world of difference.
