School me on handgun optics

[red dirt shootist]

I recently picked up a S&W M&P in 10mm, one of the performance center guns, already cut for optics. I'm not planning on competing, It will be my truck gun, loaded with full house loads. I like the "shake awake," feature, but if I'm in the truck on a rough road, will it be shaking awake? What do you like? Suggestions?

I really like my Holosuns, and on the ones I have, you can turn them off to keep them from shaking awake. Unless it’s a carry gun, I don’t really see the point in shake awake.
I also like my Trijicon RMR, but there’s a significant price difference.
