I had a small Vortex Venom optic on a Glock. Shot in our defensive pistol league with it for one season and used it at the range quite often. After a year I took it off and went back to a laser. I couldn't get used to finding the dot in that small of an optic. I shoot steel plates with a Smith 41 that has a 45mm optic mounted (it's in my avatar pic) and the dot is easy to find in that large piece of glass. With the laser, I have my open sights in good light and if there is little to no lighting, the laser is there. The small optic wasn't for me.
