Shipping & the law: Ammunition can't ship everywhere.

Always confirm your own state and local laws before ordering; checkout runs on UNUM's rails, which enforce shipping restrictions at the point of sale. Must be 21+ to purchase.

About .40 S&W
.40 S&W was the law-enforcement standard for two decades before agencies shifted back to 9mm. That shift left a lot of surplus and steady supply, so .40 pricing can be a quiet bargain when you catch it right.
Common bullet weights run 155, 165, 180 grain.
