The three ways I could think of to accomplish this would be: one, get a fiber-optic front sight--to fit the S&W revo's--from Scott Mulkerin at SDM Fabricating...he's got a website, or you can order thru Brownell's...two, get one of the S&W OEM F-O front sights, like they are installing in certain of the "AirLite" Ti's...third, have someone machine your front sight base to accept a cross-dovetail front sight--like EVERYONE is putting on 1911's these days--and go that route. Let us know what you decide!!!....mikey357
