Admittedly this is on my G17, but still, same idea compared to the stock Sig Night Sights on my Sig guns.
Can't really say I've noticed anything negative. The front sight seriously "pops" and is hard to miss. Most, and I do mean most, of my shooting is done on IPSC targets with dirt/grass backgrounds on an action range. Occasionally some steel plates. Less frequent are paper targets at an indoor range. I've never had the sights disappear or fade on me. On really bright afternoons you'd almost think the front sight was fiber optic. When it's dim above and behind me and bright in the target area, the dots pretty much disappear and leave me with a crisp black sight picture, and the rear notch leaves you plenty of light on either side of the FS to work with.

Now, in twilight conditions on shot up sub-8" plates, against dirt backgrounds, and at ranges 30+ yards I've had the targets try and fade into the dirt while maintaining a sharp FS focus, but that's the target and not the sight. At night or in the dark the tritium is like "POW" and is noticeably brighter than both the Warrens I put on an M&P as well as the Trijicons on a buddies 1911 (don't remember which Trijicons though). However, to be fair the sights on the M&P are about 5-6 years old and the ones on the 1911 are probably pushing 8, so I may just be conditioned to faded tritium.

The only complaint I can come up with is that all 3 tritium vials are green, while I prefer to have the dimmer yellow vials in the rear. Really though, that's just my user preference.

I have no intention of changing these sights until they fade, and then the reckoning is I'll replace them with a new set of the same.
