Underwood Ammo .45 ACP +P 230-grain Full Metal Jacket ammunition (part no. 337) is loaded to a hotter +P pressure spec for shooters who want their practice ammo to match the recoil and point of impact of their carry loads. Underwood Ammo pushes the standard 230-grain FMJ bullet faster than a standard-pressure .45 ACP load without changing its proven, reliable feeding profile. The full metal jacket does not expand, making it a straightforward choice for range day, steel matches, or any high-volume session where cost per trigger pull matters more than terminal performance. Reloadable brass cases mean the empties are worth saving. Among handgun ammunition, this is the +P practice round built to run exactly like the duty load it is training for.

Frequently Asked Questions

Is +P ammunition safe in any .45 ACP pistol? Not automatically — confirm your pistol is rated for +P pressures before making it a steady diet, though most modern .45 ACP handguns handle it fine.

Does this FMJ bullet expand? No, full metal jacket bullets are built for reliable feeding and straight-line penetration, not expansion, making this a practice and target round rather than a defensive load.

Can the brass be reloaded? Yes, these cases are reloadable, which helps offset the cost of running +P ammunition in volume.
