22mag is what you would want for that .....They make short barrel HP loads for it ..
22lr I would use Stinger or mini mag that would be your best bet .. if your gun will take it
I would want to use 22mag over 22lr though as mag is a wee bit more reliably and has short barrel low flash loads made for carry guns for it ..Speer and Hornday make it
edit also to add I would go a wheel gun over a semi auto if that is your plan ..Something like a LCR or one of the no lock 351c from S&W ..Simply worst case just keep pulling trigger till it goes bang
And for 22lr most of the wheel guns will in a pinch take 22short and 22 long
