I've never been happy with conventional scopes on handguns, for several reasons. What I've been really happy with are variants of Aimpoint red-dots with 2x magnification and 2MOA dots. No eye relief, parallax, or light level issues, rugged design, 50,000 hour run time on the current versions, kinda turns the handgun into a laser pointer.... Pricey, to be sure, but well worth the cost, in my experience.
