Feinwerkbau AW93 Sight Option Question

I wanted to know if there is any scope mount for the Feinwekbau AW93 pistol that allows you to easily transition from iron sights to a red dot. I have a Walther GSP with grooves milled into the side of the frame by Earl. This allows you to remove the scope ring quickly to transition back to iron sights. I've also seen grooves in frame of Pardini's which accomplish the same thing. Can anything like this be done with AW93. It seems like all the red dot mounting options require you to either remove the front and rear sight or the rear sight to mount the rail. Thanks.

Got several answers from the Bullseye-L List. Thanks.
