I wanted one of the Winchester 9410’s when the came out about 20 years ago...and the older Marlins are hard to find, and pricy if you do.
This could be fun, though.
I’ve got a .410 Shockwave; got it as a toy, but...it’s a bit more serious than I thought. The Federal OOO load performs incredibly well out of it to 50 yards, and the plated shot doesn’t deform like straight lead, giving it solid penetration. For someone recoil-impaired...it’s a serious consideration.
I also love using my buddy's .410 Beretta O/U for pheasant hunting...light as a feather, can carry it all day...and, within 20 yards, it’s got plenty of knockdown with #4’s. Fun gun.
