This talk of over penetration is kinda funny considering the 9mm actually penetrates deeper than the 40 and 45 in testing I’ve done.
When the same bullet is shot into something tougher than just plain gel, the 9mm penetration is slightly more than the 40 and considerably more than the 45.
A local officer who spent time in the morgue told me 9mm is actually the best caliber because it gets deep enough more often than the others. I didn’t believe him so I had to do some testing to see if he could possibly be right. I posted the results here on THR a couple of months ago.
