My friend Marko, who some years back pared back to just 3" K frame revolvers for main carry duty, decided to get himself a Ruger LCP pocket pistol. He even includes a photograph of it in his hand.
Hm. He claims that it's as small as the KelTec, but when I pulled my P3AT out of my pocket, my gun seemed a bit smaller in comparison.
Maybe it's just personal perception.
