Now that is gotten near impossible to focus on the front sight without my reading glasses I needed a solution for my CCW.
I've always liked the Trijicon RMR dual illumination optical sights that don't use batteries. Problem is, they make mounts for very few models of pistols.
My buddy at work has a CNC Bridgeport mill in his home workshop, so after I found a decent deal on an RMR at a gun show, and a smoking deal on a Kahr CM40 ($330) I figured I'd try to make my own mount with his help. We had to open up the rear dovetail on the CM40 go get a "standard" 60 degree angle. Since it was so far back I drilled and tapped the slide towards the front of the mount and added a countersunk 6-32 screw to help insure the stiff recoil doesn't eventually fatigue the aluminum mount at the dovetail.
The attached photo shows the result of our efforts. Function was 100% out of the box with the CM40 before installing the RMR, and function has been 100% with it installed. Since my usual CCW has been a Kahr PM40 this is a natural evolution.
At tomorrow's gun show I'll be looking for a holster I can modify to work with it.
Its pretty sad when you sights cost a good bit more than your pistol!
The beauty of this setup it the brighter the light the brighter the dot, and in dark environments the tritium powered dot is still very easy to see. For the view photo I focused the camera on the plants in the distance and then held the pistol up to show the sight picture.
