This sight does not fit s&w model 915 9mm early 90's era pistol - Meprolight TRU-DOT Smith&Wesson Fixed Night Sights

After considerable research I ended up throwing a guess and purchased this Meprolight sight set to replace original factory sights on my S&W Mdl 915. Front sight appears to be of correct size to fit, but I did not actually attempt to install it. However, rear sight dovetail wedge is clearly too to shallow and will not fit! This is a Novak style sight and will not fit the 5900 series Model 915 S&W pre-novak style pistol. I love the Meprolight brand and price, wish it would have fit.
I have since learned, purchased and installed a set Trijicon SA04 sights on this pistol with minimal difficulty. Thanks OpticsPlanet for an easy friendly exchange, and best all-around pricing.
