Description
The CorBon 40 SW 140gr DPX load is built for shooters who want a proven 40 S&W round from a company that helped shape modern high-velocity handgun ammunition. Each box holds 20 cartridges loaded with a 140 grain DPX solid copper hollow point bullet rated at 1200 feet per second, producing about 448 foot-pounds of muzzle energy. The DPX bullet is a solid copper hollow point made by Barnes, so it opens into sharp petals while keeping nearly all of its weight, with no lead core that can separate from a jacket.
This 40 SW 140 grain solid copper load is rated from a 4 inch barrel, a length that matches the compact and duty pistols most 40 S&W owners carry.

Why Choose the CorBon 40 SW 140gr DPX
- 140 grain Barnes solid copper DPX bullet
- Rated 1200 fps muzzle velocity, 448 ft-lbs energy
- Retains nearly all of its weight for deep, consistent penetration
- Designed to perform through heavy clothing and barriers
- 20 rounds per box, item DPX40140/20
Built for Personal Protection
- Carry and home-defense handguns chambered in 40 S&W
- Shooters who want a high-velocity defensive load
- Practice sessions to confirm point of impact with your carry ammo
- Keeping one consistent lot of ammo in your carry gun and range bag
Before you trust any new defensive load, fire at least 50 to 100 rounds through your handgun to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Rotate your carry ammo every so often, and store the rest in a cool, dry place in the original box so the cartridges stay clean and easy to identify by lot number.
Solid copper bullets are longer than lead-core bullets of the same weight, so fire several magazines of the CorBon 40 SW 140gr DPX to confirm reliable feeding and point of impact in your pistol before you carry it.

Why Choose CorBon 40 SW Ammo
A solid copper bullet does not rely on a lead core, so it holds its weight and keeps driving even after striking heavy clothing, drywall or auto glass. At a rated 1200 fps and 448 foot-pounds, the CorBon 140 grain DPX gives the 40 S&W fast, reliable expansion with consistent penetration.
When you compare 40 s&w self defense ammo, the DPX stands out for performance that holds up across different barriers. It pairs well with the Glock 22, 23 and 27, the Smith and Wesson M&P40, the SIG P226 and P229 and the many other 40 caliber pistols still in service with officers and private owners.
CorBon has built high-velocity defensive ammunition in South Dakota since 1982, when the company set out to solve a common problem: hollow points that plugged with clothing and failed to expand. That focus on real-world performance is still at the heart of every box. Corbon 40 sw ammo is loaded to tight standards so shot-to-shot velocity stays consistent, which helps you build confidence in the same load you train with and carry.
Concealed carriers, home-defense shooters and officers who carry a 40 S&W pistol will find this load a versatile, barrier-ready choice. Always confirm your firearm is chambered for 40 S&W, wear eye and ear protection, and follow all federal, state and local laws.
