Q: I have a Beretta 77 that I use for general plinking and self-defense. As I've grown older, I have a harder time seeing my sights. Can you help me? What do you think of using glow-paint to help you see your sights?
A: You should certainly give it a try. It's not permanent, so you won't damage the gun. I'm 64, near-sighted with bi-focals and have been a life-long competitive hand gun shooter; so I think I have the "I can't see my sight" thing pretty well figured out. On most small concealable pistols built 20-30 years ago, they sights are just plain too small to see, even back when I had good eyesight. If they are big enough for your vision, then the notch is typically too narrow in width for the front sight width and you see very little daylight in your sight picture. Getting maximum daylight showing on each side of the front sight is key to being able to get your best focus on the front sight. Your rear sight needs to be about 15% wider than the front at a minimum. So if your front sight is .125" wide x 1.15 = .143" wide for the rear notch. At about 20% wider, your front sight is really visible, but starts to get a little lost in the notch, making it challenging to shoot to maximum accuracy. It will still be good for "minute of bad guy" accuracy.
