I've carried the PPK/s and found it to be heavy for some forms of dress.
I've looked at the Ruger LCPs, but bought a Kel-Tec P-3AT. In the store, the Kel-Tec felt smoother to work the slide and trigger.
Though the Ruger LCP and Kel-Tec P-3AT are small handguns, practice is highly recommended with both.
Shot placement is paramount with a small caliber.
