Whats the point in night sights if the half life of tritium is only 12 years

>half life

You don't know what this means do you?

if you practice regularly your fucking BARREL won't last 6 years let alone 12 years, what's the problem with replacing the sights once a decade?

for all practical purposes nightsights are dead around year 7-8. past that you barely see them when pitch black.

Wrong. I had night sights mounted on a gun for 15 or 16 years. They had become somewhat dim, but were still absolutely visible in the dark.

well the ones on my glock and cz are dead. both are over 12 years now but were shit around 8 years

So get new ones. A small bit of money for 8 years of functioning seems good to me.

You probably burned them with a match or something.

im not complaining that they died thats just how it goes. im stating both were too dim to use after 8 years. honestly i dont feel the need to replace them.

my 2002 USP has dim but still visable night sights

well its not completely dead its like 20% of what it was when new. i consider then unusable since any ambient light drowns it out.

I can say with nearly 100% certainty that the tritium vials you got had been manufactured about 6 years before they met you; even if the gun was brand new when you bought it then they must have been sitting in storage as surplus for that long before being installed. I can confidently rule out QC because the guys making these can't afford to have anything less than perfect QC as a business that fills things with radioactive gas

>whats the point of living
I genuinely don't know.
Spite, I guess.

You don't know how long the shop had them in stock.

Sounds like a good deal if you can see them at all in the dark and it lasts for years.

I've considered some cheaper work arounds and it's no where near as good in any sort of way.

Twelve years after the tritium vial is manufactured, it will be only be half as bright.

I know what it means :D

I work somewhere filling vials with radioactive gas and we definitely do not have perfect QC

You get 12 years of worry-free, no buttons, no batteries, no bullshit ability to shoot your gun in the dark.

Then at the end of that time, or whenever you notice them getting too dim for you, you contact the manufacturer and arrange to have the tritium vials swapped, which they're happy to do because radioactive and EPA and all that. A few dollars later you have another 12 years of shooting your gun in the dark.

The better question is what's the point of NOT night sights

Came here to post this

That just means they'll be half as bright in 12 years, which is fine.
1/4 as bright in 24 years, which is still fine.
1/8 as bright in 36 years, which is probably too dim.

Can you not get your sights replaced in 24 years? Just replace them when you replace the barrel.

>Spite, I guess.

Heh, works for me!

Also, OP is a faggot.

>what's the point of sights
This. They don't see anything, they are more like points. What's the sight of these points is the real question.

Shelf life aside, dead trijicons are still better than most factory sights so it's not exactly like they just totally stop working.

lost point of the sight

who esle gets dreams of getting into a shoot out but your bullets do nothing so you dull out a rebar and throw it like a spear but it doesn't penetrate the other guys flesh, and the bad guy takes the rebar and impales you through the neck with the rebar, but since your in a dream you just sit there bleeding out and freaking out until you wake up screaming and checking yourself for blood.

i get these sometimes. anybody else?

All the time user. All the time.
Mostly it's me fighting my dad and my blows not hurting him when they land. We're out there Jow Forumsomrade, don't feel too bad.

it isn't our fault those pussies don't use radium.

Why even bother DAD!

Jeeez.

>do you know anything else that constantly emits light under its own power for more than a decade?
Good ol' radium has a half-life of 2200 years, though the phosphor breaks down under atmospheric exposure in a comparable timeframe to tritium's half-life. (Putting the phosphor inside a vial, as with tritium, would presumably protect it and result in a long-lasting light source, but nobody wants to mess with radium these days.) Unfortunately, we stopped using radium before the internet, so it's hard to find information on how long the best phosphors lasted, and what if any methods were used to protect them atmospheric degradation.

Really depends. Earlier this year I got a police trade-in g22 with Trijicon sights marked 05. and I can still see the rear sights quite clearly in low light -- the front sight was hard to make out even in pitch black, though. Replaced the front sight with a new one, and now I have the patrician bright-front/subdued-rear sight picture.

thanks man. that helps me feel better.

Whats the point if night sights if you cant see what you are shooting at necause its night you fuvking mongoloid

your dog will be dead long before those sights go bad.

Sector 7G?

Not even close

They're only like $110 new, that's hardly nominal.

Pistol barrels last hundreds of thousands of rounds tho.

Not even the high volume competition shooters shoot one out in 6 years.

I have the dreams with the gorillion pound trigger pull.

Unless it's a hunting dream I usually end up beating the baddie to death with the gun in the dream then wake up with a torn pillow and broken/bleeding fingernails.

>by that point it will be half as bright, but not completely dead

And even so, factoring the price of the sights themselves, averaging $10 a year isn't too bad.

>doesn’t understand what a radioactive half life is
>doesn’t think 12 years is a long time
>doesn’t know companies will replace the tritium for cheap

more like 90-100 if you are not american

>whats the point [of] of tritium
what's the alternative to tritium?

If you got ambient light you can see your sights so you don’t need night sights you fucking moron. How fucking thick can you be?

>radium paint
>You will notice that the article says that the "best quality of luminous paint" will last about three years. If you find a watch with the original radium based paint like this you will discover that it no longer glows in the dark. This is because the fluorescent material has long since been worn out by the constant bombardment of radiation, but the radium, which has a half life of about 1,600 years, will still be very nearly as radioactive as when it was new and you need to be aware of this and take some basic safety precautions.

>Luminous radium paint on dials was first used around 1910, before the dangers of radioactivity were fully understood. Although health problems in workers applying radium paint to watch and clock dials were noticed in the late 1920s, radium paint continued to be used. There wasn't a suitable safer substitute available, and military authorities continued to specify radium based paint for important applications such as compasses, instruments, gun sights and, of course, watches.

Half the price of the item 12 years later (if not longer) is really not that big of a deal when your talking about consumables being involved.

Plenty of Americans live to over 100. It's not even that impressive anymore. Why anyone would want to live past 80 is beyond me, but to each their own I guess.

Oh look Jow Forums is treating Jow Forums as its stomping grounds again

>thinks a $110 fee for something that will last 12 years is a big deal
Fuck I hate poorfags

I think living enjoyably past 80 is doable. My grandpa is like 85 and is jacked as fuck from working in his yard. Maybe by 2060 we'll have robotics advanced enough to replace fragile limbs.

>does it really need to be explained to you why being able to align your barrel with a target in low light conditions is advantageous?
Use a flashlight.

>I have the dreams with the gorillion pound trigger pull.
Shit, this happens to me a lot.

To be missed when you die. To give meaning to another persons life.

If no one was a poorfag than no one would or could be a richfag.

I had a weird dream were I knifed a viscous dog to death. It was fucked up I stabbed the shit out of him and my knife blade bent.

Whats the point of ammo when it can last from 5-200 years, dependent upon storage conditions?
