Can I handle the recoil from a 12 gauge benelli m4?

You will be just fine. Hold it tight against your shoulder as you would any other gun and go to town little man. There is no way to learn if you don't try so the best thing for you to do is get out there and go for it! When i was a youngster of about nine, and you don't need to know how long ago that was, my granddaddy had what he called his long john deuce. In short it was a double barrel 12 gauge shotgun that was about the same height as i was and he told me i could shoot it. At that age i had done little more than plink with a .22 but that thing had been hanging over the frame of granddaddy's front door as long as i could remember and i wanted so badly to shoot it. It had a flat metal butt plate and i could have sworn the thing killed me the first time pulled the trigger. But i grinned like a possum and let loose the right barrel about a second later and haven't looked back since.
