Don't worry about recoil too much. Go to the range and just watch for a bit to get a feel for how the whole thing works there. Then get your new rifle out and shoot it. Pull the stock
hard against your shoulder so it doesn't have room to kick back and punch you. You'll have so much fun you'll hardly notice the recoil. At the end of the day your shoulder might ache slightly. Minor detail.
If you're worried about handgun recoil, same thing. Just grip the gun firmly with both hands, as high on the handle as possible - look it up online how to do it - and fire. The blast seems pretty intense at first (you soon get used to it), but recoil is not a big deal. Just hang on tight for that first shot till you get the feel of it.
I went to the range for the first time yesterday. Shot my two Mosin's, an SVT-40, a 1911 (.45 ACP) and a TT33. Tons of fun. Took a few shots with my new shotgun too. I was a bit leery about recoil on the 1911, but it's not such a big deal - not a lot harder than the TT33.
The only bad part about shooting four ancient guns in one day is getting home and having to spend a couple more hours cleaning corrosive residue.
