I based my recommendation on that with the assumption that he didn't buy that particular model gun for duck or pheasant hunting
...and your assumption is most likely correct...
Although my brother-n-law, which has never hunted in his life and knows nothing about firearms, showed up at my house with his brand new/never fired 590 the night before deer shotgun season and asked "what stand he was going to be placed on in the morning".. Ya just never know!
For HD, I prefer bead or nothing as the business at hand wouldn't require sights on a shotgun. Would be more `point` shooting. This question isn't about what I prefer sooo...
Old Grump is probably on track to what peeshooter's describing.
