The Underwood Xtreme Defender Platinum Edition .380 ACP 68gr is a lead-free, solid copper self-defense load from Underwood (Underwood part no. 678). It belongs to the Xtreme Defender fluid transfer monolithic family, whose flutes force fluid inward to build hydraulic energy and whose non-expanding body is meant to shrug off wallboard, sheet metal and auto glass. The 68-grain bullet leaves the muzzle at 1300 feet per second with 255 foot-pounds of energy. A coating on the projectile adds corrosion resistance, lubricity and reduced barrel wear, according to the maker. Each box holds 20 rounds in nickel-plated brass cases.

Key Specifications

Frequently Asked Questions

Does this load work in a Smith & Wesson Bodyguard 2.0? Underwood’s own testing shows some Bodyguard 2.0 pistols can have feeding issues with certain bullet profiles because of feed ramp geometry and tolerances, and Smith & Wesson advises against flat-nose FMJ in that model. The maker says this .380 ACP Xtreme Defender has run reliably in its testing and in the vast majority of customer-reported Bodyguard 2.0 pistols. If feeding problems appear, Underwood recommends having the pistol inspected by Smith & Wesson or a qualified gunsmith.

Is the Xtreme Defender an expanding hollow point? No. Underwood describes it as a non-expanding solid copper body that relies on flute geometry and weight, so barriers such as wallboard and auto glass do not change its performance.

What velocity does it reach? Underwood lists 1300 feet per second and 255 foot-pounds of muzzle energy for the 68-grain bullet.
