“So it’s amazing how many state and federal law enforcement agencies (including the FBI) have dumped the 40 cal and gone back to 9mm.”
It’s amazing how many have hired little girls that can’t handle the 40.
That didn’t have anything to do with it. A couple of years ago the FBI released its exhaustive multi-year study of sidearms which clearly demonstrated the superiority of the 9. LEO agencies took note.
Let a few facts interrupt:
Recoil comparison 9, 40, 45 all in standard loadings and common duty pistol characterisitics:
9mm assuming 123 grn at 1150 from a 1.75lb fully loaded pistol
40 cal 165 grn at 1000 from a 2 lb fully loaded pistol
45 230 grn at 850 from a fully loaded 2.25 lb pistol
Recoil impulse recoil vel Recoil Energy
lb/sec fps ftlb
9mm .74 13.59 5.02
40 .89 14.29 6.34
45 .98 14.00 6.85
So, WTF?
Now, the ubiquitous 380 in a mini gun....90/850 12 oz
380 .41 17.43 3.54
