Tritium ( or ; symbol T or 3H, also known as hydrogen-3) is a radioactive isotope of hydrogen. The nucleus of tritium (sometimes called a triton) contains one proton and two neutrons, whereas the nucleus of protium (by far the most abundant hydrogen isotope) contains one proton and no neutrons. Naturally occurring tritium is extremely rare on Earth, where trace amounts are formed by the interaction of the atmosphere with cosmic rays. It can be produced by irradiating lithium metal or lithium-bearing ceramic pebbles in a nuclear reactor. Tritium is used as a radioactive tracer, in radioluminescent light sources for watches and instruments, and, along with deuterium, as a fuel for nuclear fusion reactions with applications in energy generation and weapons. The name of this isotope is derived from Greek, Modern τρίτος (trítos), meaning 'third'.

SOLD - Factory night sights off of a Glock 19x. I had the slide milled and replaced these with suppressor height sights in order to co-witness through the newly mounted optic. Tritium still glows bright.
Asking $50.00 OBO.

I have a set of practically new Night Fision, Yellow tritium front and solid black rear (290-313 height) for a Walther PDP-F (also fits PDP). They have been pre-fitted and then removed from a Walther PDP that I presently have for sale and just don't want to "give" them away with an already...
New / excellent condition. Bought and didn't install. I just can't choose which pistol to put it on. So I'm just going to stick with my Romeo 1 Pro's on everything.
Glass is fine, but I asked Sig to send me a spare. There will be a spare clear lense piece to go with it. I can mail that to you...
Lovely pistol. I am the 3rd owner I believe. Low round count overall but I don't know the number. I've shot a few mags through it. Shoots like you'd expect a Legion to! Sights are bright as day.
Comes with the original case, 2 or 3 mags and sorry to say NO COIN. lol
Only interested in trades...
P Series Sig suppressor height night sights. I purchased these from a fellow member but have decided to go another route. They appear to be brand new and never installed. Packaging included.
As the title says, I have a set of brand new Meprolight tritium night sights still sealed in the container.
I no longer have the firearm I intended to put these on, and Amazon considers them “hazmat” and won’t accept a return, so my loss is your gain!
These will fit an IWI Jericho or Baby...

This CZ exposed me and many others to these terrific pistols. The FIRST of MANY for me, and sadly, this one doesn't come out of the safe very often, so time to let it expose others.
This is part of the 2016 introduction of the Urban Grey series, and it is the CONVERTIBLE model, so it can be...

First one, Truglo Tritum Pro sights, professionally installed/removed from my P320 slide. These apparently have been discontinued (can't find them anywhere on the Truglo website), and are without a doubt THE BEST set of tritium handgun sights I've...
