JTQ, thanks for that link, which I just read, including the comments.
I agree that tritium sights do NOT help ID a target. And I agree that practice and muscle memory are more valuable when it comes to quick hits on a target.
I'm losing my own argument now....
For some years I have taken to blacking out my rear sight and adding a dab of Testors model airplane paint (typically white or hi-viz yellow) to the front sight to help me index faster -- I practice a lot of point shooting and having some big, fat index point out there seems to help me, esp. with my middle-aged eyes. Kinda like the Ashley Express big dots.
My reasons for the post is I am considering purchasing a Springfield Trophy Match 1911, and the sights are black on black (the front sight is smooth, not serrated, unfortunately), and that is probably my least favorite sight arrangement due to that lack of an "indexing" front sight. That's why I thought tritium or fiber optic.
But I supposed nail polish or paint could do...
I did take a point shooting class at S&W several years ago when they had a private academy, and we spent the entire day with masking tape over our front sights...
