I have shot two different Kimber 22lrs. I don't like either one. Having said that, I do own a Kimber 22lr conversion that is great.
The full Kimber 22lr is - all - aluminum and is far too light. It feels like you are shooting a cap gun. If you put the conversion on a steel frame, you have a gun that is a ball to shoot.
I love kimbers EXCEPT for the full 22LRs.
