"easy to take down & clean"
That would be a
Beretta NEOS,,,
They are a bit Buck Rogers looking but very good shooters,,,
And they disassemble and go back together with no problems at all.
I own one and it is a very user friendly handgun,,,
With the 4.5" barrel it is lightweight and agile,,,
It has very slender grips for small hands,,,
Very "
pointable" and accurate.
It's certainly not the only decent .22 out there,,,
But it is at least worth checking out.
Hope this helps,,,
