I have a S&W PPK/S it's a great little gun. It's accurate, and fun to shoot.
My wife uses it for her car gun,she keeps it in the console,and she carrys a Ruger LCP.
They are a little heavy for every day carry,but I also have always wanted one since the James Bond movies.
I also have a 1941 Walther PP, and 2 Walther P-38's
I say go ahead and buy it, you wont regret it.
