The ammo price difference is there,
but not as bad as it could be.
IE: I was considering a used .44 special,
and comparing at one popular site, using
blazer ammo as a comparison, .44 special
FMJ 200 gr is 29 bucks a box of 50.. Ouch..
That gave me 2nd thoughts about the .44 special,
despite how well I like that caliber.
At that site, 9mm is 12.00 for 50, and .40 S&W
is 14.00. So two bucks more a box of 50 at the
moment at that place. .45 ACP is 16.00.
So anyway, it could be worse for the .40..
There seem to be more deals on .40 vs some of
the other larger calibers, probably because it's
been so popular lately.
Anyway, being mine is for defense, more likely
animals rather than crooks, I wanted as much
horsepower I could get and went the .40 vs the
9mm.
2-3 bucks extra per 50 wasn't enough to
make me go the 9mm. I'll feel more comfortable
going against say a wild hog or dog with the
.40.
I would have gone .45 ACP if they made a sigma
that caliber.. Two more bucks a box, but just
that much more stop power with those heavier
wider slugs.
Still a relative bargain vs the
44 special ammo. :/
