Good budget red dot package - ADE Advanced Optics RD3-009 1x Reflex Red Dot Sight w/Mouting Plate 1911 Colt G/Standard Rear Sight&Picatinny Rail

For someone wanting to try a pistol-mounted optic without spending several hundred dollars, this is a great option.

The dot is clear, adjustments were straightforward, and the mounting plate feels solid. I removed one star because the brightness buttons are a little small while wearing gloves, but otherwise I'm very pleased.
