I know what you're saying, JMCCOYB, but with that logic all anyone would have is a side-by-side. And maybe a SxS is all that is "needed" for home defense, like a Kia Rio is all that is "needed" for transportation.
Do I anticipate that Mongol hordes will sweep down upon my peaceful domicile? Of course not.
But I tend to be cautious when it comes to home and family. I have a "it's better to have it and not need it than to need it and not have it" attitude. There's a scene in "Unforgiven" where some of Little Bill's men are loading up for a gunfight. One guy (who has one arm) loads up two revolvers. One of the other guys asks him why he's loading up two revolvers since he only has one arm. One-arm replies, "If I get shot, I don't want it to be for lack of shooting back!" :lol: 8)
Hey, it's an inexpensive modification, adds no length, adds little weight, and might just maybe somehow someday come in real handy.
