Many pistols, especially glocks, are available chambered in 9mm and 40 in the same frame size. The 9mm people often mention as advantages the recovery time/control and larger magazine capacity of the 9mm. No question about larger magazine capacity, however slight, but I have to wonder about recovery time/control advantage of 9mm over 40, when the +P or +P+ ammo is used in 9mm. To my knowledge there is no +P 40 ammo. So my question is based on your training and observation of many shooters. Do you find for most people that 9mm in +P or +P+ offers much in terms of recovery time and general control over the 40, when similar model pistols are used, eg G19 vs. G23? Do me this is an important point when dealing with a similar pistol offered in both 9mm or 40, if you intend to use +P or +P+ in the 9mm. If the recovery time/control is basically similar then the question is do you want one or two more rounds or a somewhat larger hole.
