Some states and cities — including California, New York, Massachusetts, Connecticut, Illinois, and New Jersey — restrict or prohibit online .45 ACP sales, cap quantities, or require delivery to a licensed FFL or an age-verified adult. 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 .45 ACP
.45 ACP trades capacity and cost for a heavy, slow bullet with a long track record. It runs pricier per round than 9mm, so timing a bulk buy matters more here than in the cheaper calibers.
Common bullet weights run 185, 200, 230 grain.
