New to the forum and and somewhat new to revolvers. I plan to purchase a Ruger 357 revolver, or larger. My question is this: Have any of you placed a red dot sight on one of these larger revolvers, and if so, is there anyway to keep from "modifying" the revolver itself? I dont really want to drill and tap. Hoping for some kind of mini mount. I am planning to use my Vortex Venom sight. Thanks for advice!
