Hm....
I never managed to do that (and after the beating my old M&P40FS front sight took when I had to move it....), but I did shoot the rear sight clean off a Para .45 once.... (You really have to tighten that allen screw

.)
IAC, I'm not happy with "bright sights", but it's viable. Any hobby shop should have a little vial of suitable paint for a couple bucks, too. That's where I usually end up when I want an ounce or less. Use some alcohol and a toothpick to clean the hole first....
Somebody is making a "glow in the dark" kit with little adhesive backed "dots" that may be worth a look, too. I gave up and put real night sights on the couple of guns that I thought wanted that sort of treatment. The rest of mine are "factory". I don't particularly like fiber optic, but if you can get 'em where the fiber element is very well protected (otherwise you find out quickly why they supply extra elements), it should be OK. WAY cheaper than tritium....
Philosophically, I decided that they were just bragging rights things. Then I decided that it might be nice to be able to see the sights under certain unusual conditions where you could see the target but not your sights. Of late, though, it seems that Ohio's "Duty To Retreat" law and point-shooting at very short ranges (if you're more than 21' away from somebody, you may find that it's not a good idea to shoot), sort of kill that option anyway.
Of course, my two EDC's have night sights and lasers....

The former 'cause I'm not about to take them off

, and the latter as training aids.
(Come to think of it, looking at smithcollector's post, the sights are about the only thing on my P3AT that I haven't managed to shoot off, break, or whatever.)
BTW, if you do want to paint (or "dot") the sight, it may make sense to put green or orange on the front and some other color on the rear. Your eyes can play tricks on you....
