RGV, FWIW, reference it being proven time and time again that 9mm performs best in a barrel at least 3.5" in length, and in a snub nose 9mm, might as well get a .380. In actuality, 9mm in a snub nosed revolver performs a bit better than any .380 I'm aware of. The 9mm 124 grain HST +P, that reportedly does very well in gel tests, averages 1166 FPS in my 3.5" S&W semi-auto, 1195 FPS in my 2" S&W revolver. I have a semi-auto with 4.7" barrel that produces 1294 FPS with the same 124 HST. My 3" revolver produces 1291 FPS. I don't think the projectile cares what barrel length it is launched from, as long as velocities are similar. Perhaps there are factory .380 loads that produce nearly 1200FPS with a 124 grain bullet, but I confess I'm unaware of those.

As I mentioned earlier, not trying to convince anybody of anything, just enjoying the discussion, and reporting actual results with 9mm in these little revolvers.
