Frequently Asked Questions
Buy .45 SUPER Ammo for Sale
What is the difference between .45 ACP and .45 Super?
.45 Super uses identical brass dimensions to .45 ACP but features a thicker web to handle higher pressures—around 28,000 PSI versus .45 ACP's 21,000 PSI. Most 1911s require a heavier recoil spring and possibly a supported barrel to safely fire .45 Super loads.
What guns can fire .45 Super?
Most .45 ACP pistols require a heavier recoil spring and shock buffer to safely fire .45 Super. The Glock 21, HK USP, and full-steel 1911s can chamber it but risk damage without upgrades. Properly converted 1911s are the most common reliable platform.
