Reflex sight... on Luger?

[stressed]

We all know the sights suck on Lugers. Question being on an unmatched or refinished shooter, I had a curious thought of how feasible it would be if you got a spare un-numbered repro far back toggle arm, tapped a mount into and mounted a micro reflex sight. (as linked below)

First concern would be the shock of the sight coming back each time it is fired, however if you have a quality model they are quite most "shock proof" and hold their zero, even in such a location. I can attest to this using EOtech's in the military while deployed.

Second would be the feeding of ammo. Obviously the extra weight and mass on the toggle might need more power to cycle, but these are generally almost weightless being made of aluminum. I suppose a lighter wolf recoil spring could be used if it was effected.

I'm sure many might overlook this thread as nonsense, however I mounted a reflex sight on a WWII PPS43 and it was night and day difference.
