I'm right handed and left eye dominant so want a longish gun to practice on which isn't going to blow out my shoulder. .22 lr AR Platform is also an option, but I don't have anything else in the .22caliber, so would prefer a pistol caliber if possible, 9mm preferred
Yes.
It’s five cents per round right now for the cheap stuff and there’s a decent selection of ammo types (nothing crazy, but several brands and bullet weights) at or around that price. The only 9mm within a few cents of $.25 is plinking ammo.
Plus: 22 doesn’t go out of stock at the gun store as fast as 9mm when everyone panic buys and you can get it at Walmart!
E: some good options:
The 22 conversion kit for a 223/556 ar. If you already have an ar this is a no brainer, it replaces the bolt and slides into the chamber, takes its own mags and the only difference in operation is your bolt doesn’t lock back.
Ruger 10/22: we’ll documented old gun with some quirks and a ton of aftermarket support
A clone of the 10/22: do your own research but these might fix the ergonomics/firing pin/need for cleanliness at the expense of aftermarket parts compatibility. Ymmv
Some other 22 rifle: the savage 64/62 is always around at gun stores here, and it’s fine. Don’t discount the many bolt action 22s out there, unless you’re squirrel hunting or something you don’t need follow up shots.
A work-alike of a gun you already have: almost everything modern has a 22 clone with the same manual of arms that’s used for training purposes. If you’ve already got a long gun, get the 22 version and work your shit out on it.
