If you only want the gun for slug hunting there are many options...I have a Mossberg 500 with a ported/riffled slug barrel...it gets the job done. I just use iron sights on it...had it scoped for awhile and found it cluncky and unnecessary. For the $ the 500's are a good choice, but the Remington 870's, 1100's and 11-87's also perform well with slug barrels as do the Mossberg 835's. Just depends on how much you wanna spend.
