I do not know anyone that carries the Glock 23 on their own time and their own dime. Practically everyone in my circuit of friends and associates owns at to the lowest degree one Glock 19. The handguns are identical in size and shape and fit the same holsters.
Today's defensive shooters expect quite a a bit from expanding ammunition. While that is nonmoving literal today, it's my observation that bullets premeditated to grow in reality domost of the time. Now, we privation at to the lowest degree 12" of entrance in graduated 10% ballistic gelatin, which is considered the "gold standard" in flight tests intended to dissemble what might be expected in tissue. It is not perfect, but it is the standardized and it does pretty asymptomatic replicate what is seen when increasing bullets are pulled out of physical body and blood. (My main "test media" old to be living critters called javelina, but I no longer someone access to those search grounds!
