As for others, whatever floats their boat is fine with me.
I could understand a 19L, though. (Grip length of a 19, slide/barrel length of a 17.)
Or better yet, a 26L (G26 grip, G19 slide/barrel.)
Any gun that you have in your pocket when you need it,
is better than the one at home in the closet.
More brilliant analysis from 19FortyFive.

Love my Gen 3 G19. Only semiauto firearm I have owned in 30 years that has never malfunctioned for any reason.
