    If a 4 inch barrel is used for 9mm +p 135 grain hp optimum testing what if anything is affected when that ammo is used in a handgun with a 3.4 inch barrel? Thanks in advance.

    it will probably lose a very small amount of muzzle velocity. not enough to be noticed unless a person uses a chronograph to measure it.

    I like to do a redneck water jug test, pop bottles or milk jugs.
