My next purchace will be a 9mm or a .45. I've fired a 45, but never a 9mm. With some interest I've been looking at the Star M30 9mm, 4.3", 15rds and the Springfield Armory 1911 .45, 5", 7 rds. (although I have fantasys of going into debt and getting an Arminex Trifire .45 instead {deluxe 9rd 1911} or a CZ 75 9mm) Of the two, which is louder? I had assumed the .45 would always be louder, but someone told me his hot loaded 38 super was much louder than either a 45 or a _10mm_! If you can, rate these loads for volume, loudest to quietest. (say what bbl length please) 115 gr 1150 fps 124 gr 1110 fps 147 gr 1000 fps in 9mm vs 155 gr 1100 fps 185 gr 1000 fps 230 gr 850 fps in .45 --- could you also order these rounds for volume (from experience, not just "common sense" please), loudest to quietest. 10mm, 45+p, 45, 40, 38 super+p, 38 super, 9mm+p, 9mm, 380, 38, 32 mag, 32, 22, 25. (specify bbl length or assume 5" for 10 & 45, 4" for the others.

I've always thought that a one dimensional representation, e.g., decibels,
is an incomplete part of the story regarding the subjective "loudness" of a
shot. A more accurate representation would be a two dimensional graph of
decibels/time. Even better would be a three dimensional representation of
decibles/time/frequency.
I think my 1911 .45 is louder than my 9mm High Power, but it's more of a
whoomp than a crack.
