While we are all looking for a pistol caliber that shoots like a .22lr and has the muzzle energy of a .357..... as Unkei points out it's not a rifle round.....

That said...... no one likes to get shot with anything....... and a Walther PPK/s magazine dump.... with 8+1 .32 apc...... would be close to taking a round of 00 buckshot with a tight fist size group.

I picked up a Walther(Interarms) PPK/s w/ 4 mags about 2 years ago for <$400 OTD....... would not feel under guned running errands in my Burb of the Burgh!
