Ever watch the slow motion videos of polymer frames flexing during a shot being taken? It's amazing how they whip around. So I'd suggest that the idea is a non starter before it even gets led to the starting stalls.
Open guns typically have the red dot mount secured to the frame. But there's no hard points molded into the big majority of polymer frames. I've certainly never seen such a thing but one never knows so that's the only reason I said "big majority" and not "never". And I'd be reluctant to try drilling the amount of plastic out that would allow for such hard points to be inserted. So you'd be pretty much limited to the smaller red dots that mount to the slides. But then the red dot is kicking around during firing. So that's far from ideal as well. While such a sight location works the idea of it kicking around will put you at a disadvantage to the guys running with separate mounts.
You might be able to find some up and over RDS mounts that attach to the rail under the front of the frame. But with the leverage and forces from the weight of the RDS and the distance away from the rather small mounting foot area I would expect the plastic would be come rather badly deformed and the mount would forever find itself coming loose as a result.
But I don't know what happens to them after constant pounding of the slide back and forth![]()
