Xscited about these - XS Sight Systems DXT Big Dot Sight - Sig Sauer

I have a set of these on a G17 already and they're great. Sights themselves are steel which is an upgrade in itself and they really shine- (sorry I couldn't help the pun) in low light and darkness. I've had the G17 sights for years and still glow strong. And when they're spent they're still totally usable with the low V rear sight with post and front sight with large white ring which really reinforces "FRONT SIGHT" picture / target alignment. Just make good and sure you are hitting where you want, mark the spot then red lock-tite rear site in place as instructed. You'll like em alot. It makes your side arm easy to find in the dark and you'll know where you're aiming for sure. It's just so cool to look over on the side stand and see them and think "Hunh no batteries!" ever. Once you get a set you think the advertising is really subdued for how useful they are.
