Ok, I know my answer to this, but wanted to get others thoughts. I have posted about the S&W 325 PD .45 revolver, but I also like the 351 PD in 22 mag.. My question is does anyone carry a 22 mag and is it in any way adequate ? I know that a well placed round will do the trick no matter what, and although thought is that a .40 or .45 will knock someone down is not true - I was just curious if there is any merit to carrying a 22 mag ?
