Night Sights

I am a phosphorescent pigment engineer and a firearms enthusiast. I wrote an article on the benefits, limitations, and correct application of night sights (glow in the dark, photoluminescent, phosphorescent) that I thought some of you might enjoy.

Night Sights

Enjoy,
Danny Clark

Different than tritium.

It is cheaper than tritium at about $2.50 per firearm compared to $80. It lasts considerably longer than tritium (loses about 5% over 10 years). Tritium cannot be legally taken out of the US by serviceman, even on official deployments.

Read the article for details.

If you can get it to work like tritium, you might be onto something. Other than that, I dont see it really going anywhere.

I can pick up any of my tritium equipped guns and the dots glow bright, 24/7/365, with no other light source. Thats pretty tough to beat.

That $80 initial outlay, works out to roughly $6-8 a year too, so its really not a bad deal.

$150 for "not new" handgun night sights? And a semi-custom job to install them?
Either I'm missing something or you need to find a new gunsmith.

The issue I see with phosphorescent sights is that the places I keep my guns - safes and holsters - are all quite dark. I'm not sure how they'd charge.
Tritium sights do cost a bit, but since I put them on pretty much every gun I own, I just figure them into the cost of buying a gun. It's only like $10/year

Are you sure that Soldiers aren't allowed to take tritium sights with them on deployments? I've never heard that before, and I'm pretty sure I've read lots about them being used on deployments.

I'd be interested in your source for that statement...Son #2, just home from Afghanistan might disagree. Too, what about the standard GI lensatic compass...with Tritium, I think, markers on the bezel.

Here's an ebay listing for one complete with the milspec number.

The half life of Tritium is 12.3 years. I think I can afford to replace my night sights every 10 years, assuming they weren't put in at peak freshness to have a gun that's night-ready out of the safe.

most of the time, it's $150, and the sights are not new. So it's more like $30 per year, because replacing them is a sort of semi-custom job. Still, it's chump change, well worth the expense.
I do my own, so it costs me what the sights cost, which for the last couple of sets, was $68 on sale. They were new too, and were dated the same year as they were installed.

Replacing them is easy enough, and so far, I usually recover half the cost of a new set, selling the old ones on EBay. That alone had paid for the sight tools.

Of the 6 sets of used sights Ive replaced, I have yet to replace a set that were totally dead, and most were beyond the 12 year warranty date when they were replaced. Even then, while not as bright as new, they still glowed, and were visible in the dark.
