Re: Walther PPS for conceal carry?
I carry a PPK/S as a backup or when I don't feel or can't carry my Glock 40 S&W. Just make sure you have good magazine's that don't jam. Make sure just like any carry weapon, you are proficient. Myself, the FBI, CIA and 80% of the nation's police force don't like 9mm's for just cause. 9mm like the .380 is a good backup weapon.
Woops, forgot Secret Service.
