At 63, I've been battling the disappearing, or blurry, front sight for a while. I mentioned it to my vision specialist who professes to shoot a little himself. Hey says the doc, get yourself some over the counter readers, some with ground glass lens if you can find them, but cheap is fine. He suggested getting a pair with as much surface area as possible just for coverage - and sticking them under clean goggles if I could stand it. Admittedly, I don't do the later - but I only use them on paper targets. And viola, the front sight is back. While I wear true prescription reading glasses, they didn't work well. But I bought 1X, 1.5X and 2X - the 1.X worked perfectly! Anytime I can shoot a group like accompanies this post, I'm thrilled. And this with a deep U notch rear and gold dot front sight off sandbags thrown on the truck hood at a measured 20 yards. I put this post here because the reader glasses are gear - it's not a review, but a piece of kit. If you're having issues with pistol groups, give cheap readers a try. I don't like them on bright sunny days, my eyes are sensitive to bright light and I prefer my ballistic shades. For the record, the gun was an Ed Brown Kobra Carry LW. The load an old Wilson test ammo recipe of Bullseye under a 200 grain SWC moving jut about 830 FPS at the muzzle on repeated measurements. Seating depth was a consistent 1.250-1.245 - that's as tight as I can keep range brass.
