I have a 625 that I shoot in IDPA competition. Would really like to find a front night sight for the indoor matches. Are they available and if so where?
Meprolight night sights are very functional. They make a set with an insert that replaces the red ramp insert on the front sight. And they make a set with a pin on front sight, that replaces the front blade. The rear sight replaces the rear blade on both types. They're not very hard to install, and come with good instructions. The two guns below are with the red ramp replacement type. I don't know if they sell just the front sight. The sight picture is really improved for both low light and daylight. It has a wider rear notch that really enhances the sight picture, at least for my shooting. Hope this helps.
