This Underwood Xtreme Defender Platinum Edition .380 ACP +P 68gr load is sold as a 20-round box (Underwood part no. 679). The Platinum Edition version of Underwood’s Xtreme Defender in .380 ACP +P wraps the same 68-grain solid copper projectile in a protective coating. Rated at 1400 fps, the load is built for small defensive pistols, and the coating is intended to keep the copper bright and feeding smoothly through long-term storage. The flutes do the wounding work, so the bullet does not depend on expansion to be effective.

Frequently Asked Questions

What is different about the Platinum Edition? The Platinum Edition finish is a coating that Underwood says protects the copper from oxidation during long storage, adds dry-film lubrication for smoother feeding, and reduces barrel wear compared with a standard monolithic projectile.

Is this a +P load? Underwood notes that .380 +P ammunition is loaded to higher pressure levels, so make sure your firearm has the necessary chamber support for this round; if you have any doubt, have a gunsmith inspect it or contact Underwood.

What box size is it? Each box holds 20 rounds.
