I like the .30, but ammo is expensive and sometime not readily available... 9mm, when not on, "Panic sale!" is relatively cheap...The .30 is really pretty snotty when shot out of a long barrel, 6 inches or better... but, according to the whole world less the Swiss, 9mm has more energy for attack or defense?? BTW, check your want add, I have something that might be of interest to you... til...lat'r...GT
