And where is the KAHR P380 in that comparison?
Actually there is NO comparison between the P380 and anything Glock or even Ruger - certainly not the "new" Ruger LC-380 which is a virtual behemouth compared to the LCP.
The Kahr P380 is smaller by far than either of the guns depicted by the OP...not as light as an LCP but only by a slight margin, and it does have the best DAO trigger ever devised by the mind of man.
The new Glock .380 is a MONSTER in comparison...and too pricey to compete outside the world of people who buy new guns just to have something different.
