Night Sight advice for a Sig

[WrongHanded]

A while ago I bought a P224 in .40 S&W. It was new, but made back in 2013-2014 (can't remember exactly, but it's on the box).

At some point in the first week after shooting it a few times, it occurred to me to check the night sights. The tritium tube of the front sight barely had any glow at all. I called Sig, and managed to return the gun under warranty, but had to pay for the shipping label.

The gun was returned fairly quickly, and though I can't be absolutely certain, I'm reasonably sure that - as any of us would - I checked the new sight in a dark place, and found it to be as bright as it should be. Fast forward to yesterday, and the front sight is no longer illuminated. I haven't dropped, hit, banged, or in any way abused the gun. So I'm struggling to understand what's happened here. But I would very much like functioning night sights on the pistol.

In addition to this, both the original and replacement front sights were #8 in height. Yet the gun would shoot high with any grain weight of .40 I put through it (180-155gr). At the time I had the sight replaced, I was trying to get a .357 Sig barrel (I finally did) and figured a lighter faster bullet would hit more towards POA. Yet it is still hitting high (just not quite as high). This may possibly be due to the rear sight being quite a bit taller than the one on my P229 .40, which has the same #8 front sight and only a slightly longer sight radius. There are no obviously numbers on either rear sight.

This presents me with the opportunity to replace the sights with something that will put POA closer to POI. But I don't know what. Trijicon has some fancy looking night sights. But it's been a good long while since I bought any replacement sights for a semi-auto, so I'm not sure what's available. Thoughts and input would be very helpful. Thanks!

I have a P229 with Truglo TFX Pro day/night sights installed. No regrets wishing that I would have installed Trijicon, XS, Ameriglo, etc.

They are plenty bright at night and I do like the fiber optic light gathering enhancement to the sights; seems like I always have a glow. My eyes really pick up the orange ring on the front sight. Self installation is not difficult either, I've installed 4 sets.

Thanks WVsig. I actually already saw that.

As I said, no number on the rear (but very different than my P229). And if a #8 front works with .357 Sig, I shouldn't be shooting high like I am. My other Sigs all hit pretty much behind the front sight. I think Sig calls that a combat sight picture, Don't they?

I can't be sure about the numbers because I'm not a great shot, but cutting the bullseye horizontally with the front sight hits about 8" high at 25yds with a 180gr .40, and around 4" high with a 125gr .357 Sig.

The front sight on my P938 went dead too it's only 2 years old I also need to replace it

Well I'm sorry to hear that. Perhaps it's a failure in a certain batch of sights that Sig has.

I'm going to try the TFX Pros. I found a set on Optics Planet for $117 in the #8,#8 configuration. They look like a very good option. Thanks!

That's pretty crappy, yet another new SIG issue?

Though that's more outsourced parts.

I'm okay if that's the only issue I have with it

I like Tru Glo TFX Pro night sights. It's also hard to go wrong with the classic Trijicon Bright and Tough night sights and the Trijicon HD night sights. Something else that may be worth a gander is the Sig X-Ray night sights that Sig installs on the Legion pistols. I love those sights on both my P226 and P229 Legion and they're dead on the money.

Tritium is a radioactive isotope of hydrogen that has a half-life of ~12 years. So the brightness (which may not be in a direct relationship to the amount of Tritium) will be about half as bright in 12 years if it's a 1:1 relationship to the amount of Tritium initially used. However, The material is held in storage prior to being used for the sight coating. It decays (loses strength) throughout the lifetime of the substance so it may have already lost some of its luminescence prior to the manufactured date of the sight.

These sights are only good for a relatively short period of time before the brightness is inadequate. I believe that Sig has a disclaimer to that effect. (?)
