I agree as far as carrying goes. I have a Sig P226 in 357Sig for that. This would be a fun gun for me. As far as reliable rim ammo, it depends on the brand. I used to compete with 22 rimfire for many years. I only had reliability issues with old ammo, ammo that has been stored in a damp area or cheap brands(cheaply manufactured). I personally like Eley and Lapua 22 ammo for consistency and accuracy.
