red dot optics and / or pistol scopes became legal in NRA conventional pistol competition (AKA Bullseye) around 1989. Pistol scopes were first & then soon thereafter, Aimpoint came out with their red dot.
I started with a 2X Bushnell scope, then a 2x Leupold, then an Aimpoint. Still have the .45 with the IMI knockoff of an Aimpoint on it. That knockoff was sold to competitors by the then National Champion in conventional pistol.
