I keep threatening to buy a pistol with some type of RDS before my eyes require it due to age. I fondled a Kimber Aegis with their “OR” system and a Vortex Venom at a local fun store and it seems to be a good setup to my uneducated eye.

They also make a KHX OR that looks like it would be interesting

Anyone here have any thoughts about the way Kimber accomplished bolting a RDS on a 1911?
