I really like the I-dot set up. Had not heard of this brand. Very reasonably priced as well. Have to look into it some more. Hopefully others will chime in here.
I read somewhere about it being possible to crush the tritium vial during installation. Seems odd that 3 sets would fail in a row all within days of the install. Assuming the same sights were opened and not installed on a gun would they fail in 3 days? I am quite sure they would not. That leaves the install. Sig sights are tight. I have had the pusher try to lift me off my chair trying to turn it lol. I now do as Willard suggested and work the sight a bit. From a machining stand point it seems like they come a hair oversize expecting a bit of final fitment/finishing. No one does that tho they just get a pusher and FORCE them in and go on and on about how tight Sig sights are. They are only as tight as you want them to be. Everyone worries bout goin to far and ruining the front site tho.
Upon closer inspection, I suspected this was the case, the last sight looked a little forced as some materials on the sight seemed to be pushed up. The other sight that went bad didn’t look as forced. Still, it’s weird that would be enough to damage the vial. Anyway, they’re sending me a label and will look at it. They’re in Texas so hopefully won’t take long. XS has great customer service I will say.
Honestly, they were the FIRST manufacture, that I can recollect, advising how to "slim" their sights. Honestly, it wasn't an "option" I had considered before, but I did as they advised! Most sights are slightly oversized to insure they will fit, even older worn dovetails. I didn't take as much off, as their video suggested, as using a pusher, I didn't need to use their version of supplied "Loc-Tite".
