You really can't go wrong either way. I wouldn't let a measly $50 determine which pistol you get. I owned a Gen4 22 and was a superb shooter.
Edit: BTW. I even shot it with the 31 barrel and wow felt great. Ejections are strong with either caliber and you won't or at least shouldn't find problems with BTF like some of the 9mm's do. Even then that doesn't bother me. my Gen4 19 sometimes spits brass at my forehead with strong loads, but I never had a failure of any kind. Good luck with your purchase.
