Great little red dot - Crimson Trace CTS-1550 1x 3 MOA Reflex Red Dot Sight

Great little red dot. Installs directly onto my Kimber Mako R7, alignment posts in the slide fit the registration holes on the bottom of the red dot for a precise and repeatable fit. Nice because it's the exact width of the slide - so it doesn't hang over the side of the slide like other red dots. Red dot has a good size for me, good brightness in all light and easy to pick up. Slight field curvature at the edges if you specifically look for it, let's be honest, but this is not noticeable when aiming. Also, slight greenish tint if you look for it, but again let's be honest, this is not noticeable when aiming. The battery installs underneath, so in 2 years you'll be taking the sight off to change the battery - common CR2032 - and re-zeroing. This is acceptable for me because of the compactness of the sight that fits the Mako R7 so exactly. Use the supplied allen key wrench for zeroing adjustments. Once set, holds the zero precisely for years.
