If you want new, check out the Vortex PST 1-4, SWFA SS 1-4, or Trijicon TR-series 1-4 or 1.25-4.

If used is ok and you're patient, you will find a USO SN4 1-4 or NF NXS 1-4.

Red dots are light and certainly faster because there's no eye relief or parallax considerations. It a personal preference between the two.

If you see yourself offhand shooting <100 yards mostly, I'd go for the reflex. If you see yourself pushing 100+ more, I'd go for the 1-4x.

Highly debatable but worth considering -- if a reflex over a 1-4x is the path, would most people actually prefer to pull the dot off and iron sight it out to 300? I know I would.
