Funny you should say that. While ordering my EPS carry today I was looking at the cans in the display case and inquired about costs on a decent 9mm can. He said I should start with a 22 just because “they are just too much fun! Put one on a 22 and it just makes you smile”.
That may be my next set of upgrades once I have updated optics (still considering LPVO vs magnifier vs just let my AR be with its red dot as its set up for close quarter defense). Unless a gun grabs me and makes me buy it
