To shoot 9mm out of a 22/23 or 31/32, one should change the barrel, the magazine, AND the recoil spring. This is especially true for the Gen 4's, since the mechanism is so different.
Someone earlier wrote that for outdoors/hiking they go back to .357Sig from .40S&W. The ballistics are similar enough between the two that I don't understand the difference. Any thoughts, anybody?
