Most 22 or 22 mag revolvers do have crappy triggers. Lighten them may or may not work, you are to find the right ammo.
How about a 38 with wad cutters, cowboy loads or something very lightly recoiling? That's easy to do.
Or there are the 32s as there are very lighly recoiling loads. A 32 revolver isn't that common but they do exist.
