    Mas,
    Do you recommend the same SD 9mm ammo for 16" barrel carbines as you do for handguns?
    Thanks for all your expertise.

    Been a long time since I chronographed 9mm rounds out of a carbine. I can tell you that 147 grain subsonic performs better out of longer barrels as with submachine guns, and the super-fast 9mm loads might gain TOO much velocity out of a long barrel, sacrificing some degree of penetration.

    Hoping that's helpful,
    Mas
