1911’s in general, 9mm versions specifically

In theory, yes, though I'd be sure to look through the sight before buying it to check for bloom, especially if you have any astigmatism or eye issues. Generally speaking, the cheaper the RDS, the lower the quality the emitter and the lens coatings. Learned this the hard way - on paper, one of the holosun enclosed pistol sights seemed excellent for a CCW gun, but once it arrived, it was literally unusable for me, the bloom was so bad. Green dots also seem to be worse for it than red dots. Thus far, I've been 100% satisfied with crispness of the dots on 2 Trijicon pistol RDS's, and an Aimpoint M4S.

As long as the dot's fine though, yes, in dry fire a cheap optic should be just as good as expensive in learning trigger press.

That said...there's just no replacement for quality, especially when you end up spending more eventually to do it right the second time. I can't give a recommendation on what cheap ones might work, but I know I've never had a Trijicon fail in about 50k rounds across 1 RMR and 1 RMR HD. Admittedly though, my data set on RDS's is pretty small, with just the two pistol optics.

I would only be using it for dry fire if I went cheap. Thanks!

When you say green's easier to see - we talking ability to pick up quickly, different light, etc, or are you getting less bloom with green?

Both I guess. I would loose a red dot on a bright sunny day unless I had it cranked way up. Which then would start to bloom out..

Also. Only green I have really played with has been that 6moa dot. So that might skew things a bit as well

You say that now....
