Stop in for a cup of coffee

I think the .22 has more kick but it be the difference in experience.

I am not really one who knows guns real good, in fact i never used to like them but now i work around a lot of law enforcement so they are rubbing off on me

A 9 mm will go in one side and out the other....

A .22 will go in, but not enough power to exit, therefore it bounces around inside the skull like a pinball to do more damage to the brain....

(I'm not a gun guy, but watch enough forensic file shows to pick that up....)
