That seems about right. Answer this for me, I was watching NCIS reruns yesterday afternoon, and they said that 1 9mm used a 120 grain bullet, and 2 it was a slow round. I always thought that 9mm used three weights most common being the 115, 124, and 147 gr. weights. I have seen some that were swagged and made to 120, but would they have been talking about the retained weight from say a 124 gr. round? Also with those numbers that you got, would you classify that as slow. Bear in mind that my beloved 45 acp leaves a 5"bbl with 230 gr. at a leisurely 850 fps or so?

If it was on tv it must be true.

I don't discount that little tidbit at all.
