After seeing hikok45's youtube video showing that you basically need to aim with a shotgun at home defense ranges, I'm a lot more concerned about being able to swing my 590 around and score the first hit should someone ever get in the house. I think my 590 is drilled and tapped for a scope base, and if it is, would a Streamlight TLR-2 be a good choice to mount on a piece of rail on top of the receiver? I would think the barrel would block a section of illumination from the light, but the laser would at least help ensure the first trigger pull is effective. What do you think? Wanna kill these ads?
