Adjustable sight revolvers are readily available from S&W and Taurus and Ruger and Colt. Specifically, Model 10 & 13 S&W fixed sight revolvers have analogous adjustable sight revolvers in the models 15 & 19, and then those adjustable sights can be replaced with taller fixed sights if one desires.
Yes,I know that the whole product line isn’t always available new, but the point remains. While I enjoy shooting my target sighted revolvers, when I actually carry one, it’s almost always one with a top strap groove rear sight for the reasons mentioned by SCCY Marshall.
