Whig,
If you look at my old thread on my sporterized 35/40 it has a red dot sight. They are quick to get on target in heavy brush. Just the thing for pig hunting. Since mine has a 3 minute dot it will not let you shoot  fine high scoring targets. Also mine does not work in moonlight at all. With my 4 power Weaver I could get one shot off on a pig in near full moon situations. Would take several minutes of setting the cross hairs on the pig then lifting so you could see them again. No contrast with black pigs and black cross hairs at night. Also the weight of the red dot is only a couple of ounces so recoil will have little tendency to move sight around.

Tom, pictures please. Would like to see yours also.
