View attachment 457596Here's mine in 9mm not 40.
Yes, all M&P sights will fit the SD/SDVE series guns.I think all the SD models have a dovetail mount that takes a M&P rear site, anything that fits a M&P will fit the SD I believe. I have a red dot on my SD9VE , love it. The first one (ADE) I bought only lasted 2 sessions at the range (you get what you pay for). The one I have now has a lifetime warranty and I am very happy with it , Vortex Optics Viper Red Dot Sight - 6 MOA Dot . I used the adapter from the first red dot and that worked fine.
