"Pistol sights for old eyes"
When I first started out, I liked the 3-dot sights, but my preferences evolved as I learned more and trained more. I tried out many pistol sights over time. But am pretty much settled on plain black rear sight with no dots or lines. And a pretty side aperture so I can see 'light' between the notch and the post of the front sight. And then the front sight has something. It's not just black, there is a dot of some kind on up there.
"Three dot sights are probable not the best pistol sights for old eyes." Yeah, I've come to the opinions they aren't the best for any eyes.
And it turns out, as my vision deteriorates as I age, (and it is...) that is a decent setup. But hell, I'd go for that with my 30 year old 20/15 vision.
I've always liked the idea of tritium sights for low light shooting, but if the light is low enough to need glowing sights it's too low for target ID. 'Liked,' past tense. Yes, tho, my bedside gun has a glowing front sight. Anyone in the house besides me in the dark is a legit target. No way my rear sights of the bedside gun are becoming part of it in low light. They don't glow. But my other easily accessible firearms available have flashlights on them. A light bright enough to make the room light enough to use regular fiber optic sights. That is probably your best bet. That and knowledge of your home turf in the dark.
My eyes, personally, are still pretty good. I can drive ok without glasses, I just don't prefer to. I have to get too close to street signs to read them. So, shooting without glasses is also not a problem for self-defense ranges. I don't keep my glasses in my bedroom. I don't normally need them when to home. Just for TV to look good.
"How about a red dot on your pistols, T-Bolt"
Meh... That would require serious smithing. None of mine are ready for a mount. And then it would require a buncha training with the sights, and then practice to get good. I'm not agin the idea, but it would take some doing. But Tam believes in me! She thinks I can do it! And if she is for me, who can be against me?
"Training?"
Oh yeah, I still make those muzzle circles like a noob. But I've also seen noob later get the knack, and red dot like a house afire.
"Ya know, T-Bolt, you can just BUY a pistol with the optic dovetail already cut on the slide..."
Quiet you! That's enough of your sass.
