I like the 42, It's small enough to disappear with a pocket holster in the front pocket of a pair of overalls (kinda hard to IWB carry a G19 in overalls LOL) or for a trip to the doctors office where I might have to undress, but big enough to easily find the grip without fumbling around and to shoot accurately. Spare mags are easy enough to conceal as well. I love my g42 for when I have to downsize and pocket carry. I have found that yes indeed there is such a thing as too small.
