The problem now is the cost and availability of ammo. You are looking at 50- 60 to cents around now for 9 mm. If you can find it. You can still shoot six mags of 22 for the price of one mag of 9 mm.Honest opinion? I would ditch the 22 and pick up a used full sized 9mm.
Recoil is very manageable. Ammo is more than 22 and less than 380
