RE: Red Dot or Crosshairs?
For hunting, I would go with crosshairs. I have a S&W 22 that I use for squirrel hunting and I initially put a red dot on it. I never felt comfortable with it. Went to a regular scope. Now I can hit 'em in the head pretty much every time.
I also had a 357 with a red dot on it for a while. Sold it, because I couldn't hit anything CONSISTENTLY with it. Could have been me.
I love the crosshairs. It is just what I have grown accostomed to. Maybe you'll be different.
