Underwood Ammo 129 38Special+P 125Gr Jacketed Hollow Point 20 Per Box/10 Case

Underwood Ammo 38 Special +P 125-grain jacketed hollow point ammunition delivers reliable stopping power for self-defense in a classic, proven caliber. Built on nickel-plated brass cases, these rounds are non-corrosive and reloadable, giving you flexibility for range work or serious carry loads. The 125-grain hollow point is engineered to expand on impact while maintaining the velocity and energy needed for effective defense, traveling at 1250 feet per second with 434 foot-pounds of muzzle energy.

This 38 Special +P load sits at that sweet spot where shootability meets performance. It's supersonic, meaning it cycles reliably in any .38 Special or compatible revolver, and the moderate recoil makes it manageable for follow-up shots—critical in self-defense scenarios. Whether you're running it through a snubnose revolver or a full-sized wheelgun, you get a round that's been field-proven and trusted by shooters who take their carry ammo seriously.

Underwood built these rounds with suppressor use in mind, so if you're running a can, you won't have any issues. Each box contains 20 rounds, and the 10-box case lets you stock up without breaking the bank. The lead core and jacketed construction mean reliable expansion and penetration, and the quality control you'd expect from a manufacturer focused on serious ammunition, not just commodity load-outs.
