I agree with the Jeepster. I bought a Canik TP9 Elite. Relatively cheap and came with a Red Dot just to see how I get along with it. We put Red Dots on my old Departments Glocks and I always struggled to find the dot.
The Canik however just happens to be the right grip angle or something where the dot is easy to find.
I'm not a big Red Dot fan but for us experienced fellas (old) with questionable eyes they are a plus. And officer scores increased considerable.
The slide cut should be fairly easy for a good machinist, just like open heart surgery is easy for a good doctor.
Not sure there's enough room but I'd opt to keep the iron sights as well as the red dot. Maybe even have a plate made so you can take it off if desired. Not sure there's enough room on a Kahr. Probably not. A co witnessed red dot would be a plus but don't see how that could happen. Would need tall suppressor sights.
