After shooting my 41 Magnum Ruger Blackhawk a few times, I decided that it could use an optic to shoot it more accurately, since I'm not that good with open sights. Earlier this year, Whitworth mentioned that Weigand offers a no-drill mini mount designed for small reflex style red dot. I've considered an Ultradot L/T and Leupold Deltapoint, and my local store had a Vortex Venom that looked pretty nice.

What sight would you recommend?
