422
22A
I have a 622 (same gun, different finish). Shoots accurately and can be fun, but finicky on ammo for reliability. Bummer for a new shooter you're trying to teach to have frequent feeding issues and misfires.
Also a PITA (Pain In The Butt) to clean. The baked on silver finish on my 622 developed significant blemishes, even with proper care.
Haven't tried a 22A, but I thought the barrel arrangement was cool. Didn't care for the cheesy grip.
