Description
The CorBon 40 SW 165gr JHP 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 165 grain jacketed hollow point bullet rated at 1150 feet per second, producing about 485 foot-pounds of muzzle energy. CorBon designs its JHP bullets to open reliably, even after passing through heavy clothing, and to transfer energy quickly for dependable stopping power.
This 40 SW 165 grain hollow point 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 165gr JHP
- 165 grain jacketed hollow point bullet
- Rated 1150 fps muzzle velocity, 485 ft-lbs energy
- Designed for reliable expansion through heavy clothing
- Reloadable brass cases with boxer primers
- 20 rounds per box, item SD40165/20
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.
The 40 S&W produces a sharper recoil impulse than the 9mm, so regular practice pays off. Fire several magazines of the CorBon 40 SW 165gr JHP to confirm feeding, ejection and point of impact, then use practice ammo of a similar weight to build your skills with the same pistol you carry.

Why Choose CorBon 40 SW Ammo
The 165 grain weight is often called the sweet spot for the 40 S&W because it balances velocity, penetration and recoil. CorBon rates this JHP at 1150 fps and 485 foot-pounds, giving it more speed than typical 180 grain loads while keeping enough bullet weight to reach adequate depth through heavy clothing.
When you compare 40 s&w self defense ammo, look for a load that runs reliably in your pistol and gives consistent expansion. The CorBon 165 grain JHP 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 law enforcement 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 balanced, hard-hitting choice. Always confirm your firearm is chambered for 40 S&W, wear eye and ear protection, and follow all federal, state and local laws.
