Egads, all this testosterone over who uses what CALIBER? Jeez, all that chest puffing... it's all about choice, plastic, aluminum, steel, 9,40,45,10, and about shot placement, something the overwhelmingly vast number of us will never need to know unless we're shooting gun games.
Y'know dissing a choice for larger calibers because the herd went the other way gets old, so... Just for fun as a dyed in the wool larger caliber guy...
A. Who trusts their life to a round which a parrot can poop bigger than?
B. There's no excuses for a bigger hole size.
C. 11/12 rounds or 18/20? if you plan on missing a lot... take the 20 that's cool.
As far as... "but 40 is just fine too. I can't say I'm a huge fan of it since it doesn't really excel at anything."
No? Really? NOT ANYTHING? Entry hole and scoring means nothing? I'll bet you haven't been to several hundred matches in various disciplines... If you have, you weren't watching.
On a windy day and poppers set not to blow over fail to go down with the cartridge that won the heart of ms Bambi secret agent (and diminutive men of which I am) some don't lose on those grounds.
Bang, clang --- bang bang, clang clang --- bang bang bang, clang clang clang, and maybe THUD.
At a pin match when there's two empty 18 round mags on the loading table and "dead wood" still of the table, the .40 is more forgiving of less than wonderful shot placement. Note a bowling pin is 3 pounds 6 ounces not a man's weight (but a good representative of a CNS hit) and pins are not shooting back, only the clock, you and and your gun.
So much for "knockdown" power.
