Re: 3 Gun optic advice
To the OP,
Money being no object, the S&B Short Dot is awesome.
I ran an ACOG for a long time and did VERY well with it. That said, I started playing the Trijicon TR-21 (I think) with red triangle. 1.25-4x and it was cool. Picked up a Meopta off a prize table and never looked back.
For a couple hundred bucks more you have a safari grade scope that can take a beating, glass is awesome and the reticle is very friendly (K-Dot Reticle).
I can highly recommend either CS Tactical or SWFA to get you squared away.
