Speaking of 410...(and possibly helping you justify the purchase, LOL)
My father in law bought my young son a BrazTech (Rossi) 22/410 combo for Christmas...Here it is (I love this pic),
Anyway, my oldest son and I had an absolute blast with the 410 barrel a few days ago...we shot up 5 boxes of shells while hand throwing clay pigeons. I beat him bad, real bad...he's a heck of a shot with a rifle but never really messed with shotguns much. I bird hunted a lot when I was younger...
At the end he was starting to hit them pretty good though...it was fun, no sore shoulder, lots of laughs.
My young son also shot it once with the 410 barrel...I was helping him hold it...He grinned real big and said "load it again". I didn't load it again, didn't wanna overdo it, he's only 4. I wish I had a video of him describing the recoil to his Papaw...he was so serious when he was telling him about it, but it was hilarious.
