Fit on mine was great - both in the dovetail and for the RDS (I'm using a DPP in my setup). Not sure of the Springer mount is the same, but the Henning mount has a rear set screw that adds extra support for the mount so it's not relying just on the dovetail for support.
I'm sad they removed the rear cocking serrations, but they must have needed to.
Unless my eyes are letting me down more than I realize, in the photo, looks like a Trijicon, definitely not included unless the gun is going for about 800.00 bucks..... lol Other than the Sigs, any pistol I've seen with milling done for a red dot doesn't include the dot but sometimes has the plates for various brands of optics.
The Liberal Party believes that terrorists should get to keep their Canadian citizenship ... "because I do,”.... Trudeau
As soon as we know more on mounting options I will place a preorder!
