Red Dot Sight for Sig 226

[1shotwonder]

I am looking to put a red dot on my 226 as the eyes aren't what they used to be what are my options for this without any gunsmithing being required?

Burris will mount to your rear sight dovetail, id suggest the 3 over the 2

Cadex makes a Burris mount that will fit in the standard 226 dovetail. OST was blowing them out for $50 (?). If you have a 22LR or Elite series, the dovetail cuts are different sized.

Humm, I wonder if the Vortex Venom has the same footprint as the Fastfire?
