G2 Research Civic Duty 40 S&W ammunition pairs a 122-grain solid copper projectile with a proprietary trocar geometry that triggers controlled radial expansion upon contact with fluid or gel media. Leaving the muzzle at 1000 feet per second from a 5-inch test barrel, this load generates 270 foot-pounds of energy while remaining entirely lead-free — addressing both terminal performance requirements and indoor-range compliance constraints. The petaled design peels outward on entry, creating wound channels characterized by broad diameter and limited penetration depth, a profile intended for self-defense scenarios where barrier overpenetration poses liability or safety risks.
Built for the Box
G2 Research machines each projectile from a single billet of copper, eliminating core-jacket separation and ensuring uniform expansion across production lots. The nickel-plated brass cases resist corrosion during magazine storage and feed reliably in semi-automatic platforms chambered in 40 S&W. Boxer primers permit reloading, though the solid-copper construction and trocar cuts make bullet recovery impractical after firing. Each 20-round box ships with DOT hazmat surcharges applied.
The Numbers
| Spec | Value |

| Caliber | 40 S&W |
| Bullet weight | 122 grains |
| Bullet type | Solid Hollow Point (G2 R.I.P. trocar) |
| Muzzle velocity | 1000 fps (5″ test barrel) |
| Muzzle energy | 270 ft-lbs |
| Rounds per box | 20 |

| Reloadable | Yes (cases) |
| Intended use | Self-defense |
| Country of origin | United States |
This load sits within the defensive ammunition segment of the 40 cal ammo category, engineered for shooters prioritizing extreme expansion over deep penetration. The 122-grain weight sits at the lighter end of the 40 S&W spectrum, trading momentum for velocity and radial wound profile.
Safe Handling & Compliance
Federal law requires purchasers to be at least 21 years old for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Observe the four universal rules of firearms safety at all times.
- Verify current state and local laws governing ammunition purchase, possession, and use in your jurisdiction before ordering.
- Conduct function testing with defensive loads in your specific firearm before relying on them — feed geometry and recoil impulse vary by platform.
