Does anyone use one on their carry gun? If so what maker?

I use an aimpoint micro both on my m&p and on my glock 19. I had a company by the name of unity tactical do the slide work for me. They make a system they call the ATOM mount that will accept many different reflex sights. Fits well in my crossbreed. I find it helps when shooting in awkward positions when looking through sights aren't possible.

Here is a thread from another forum:

And their web site:

If you get a reflex-style sight, make sure it is a reputable maker. I have had several cheaper reflex-style sights that were borderline useless (wouldn't hold zero, broke, etc.)

C-more and aimpoint are good choices. A lot of the race-gun guys use a C-more.
