G2 Research Civic Duty 40 S&W 122 Grain Lead-Free Expanding Solid Copper Ammo - 20 Rounds

The G2 Research Civic Duty 40 S&W self-defense ammunition is engineered for shooters who prioritize controlled energy transfer and barrier performance in home-defense and concealed-carry scenarios. This 122-grain, lead-free expanding round combines G2 Research's proven Trocar solid copper projectile design with a focus on reliable expansion and minimal over-penetration—critical concerns in close-quarters defensive situations where unintended targets may be nearby. Each box contains 20 rounds.

The Civic Duty round's solid copper, lead-free construction expands to roughly 2.5 times its initial diameter upon contact with soft tissue, converting nearly all of its kinetic energy into terminal performance rather than depth of penetration. G2 Research's design philosophy centers on retaining 99.9% of projectile weight inside the intended target, significantly reducing the risk of over-penetration that can compromise safety in populated environments. The round's barrier-defeating capability—inherited from G2 Research's R.I.P. ammunition line—means it performs reliably through common obstacles like heavy clothing, drywall, or vehicle glass, then transitions to controlled expansion in the intended target.

If you're evaluating ammunition for personal defense in tight quarters, competing against mass-produced bonded hollow points, or seeking a lead-free option that doesn't sacrifice stopping power, the Civic Duty round addresses the real-world tension between energy transfer and over-penetration risk. The 40 S&W chambering remains popular among defensive shooters for its balance of capacity and terminal performance in compact and mid-size platforms.

Key Features

• Solid copper, lead-free projectile—environmentally safer and compliant with lead-free range requirements
• Expands to approximately 2.5 times initial diameter for consistent, reliable expansion
• Retains 99.9% weight in target, minimizing over-penetration risk in close-quarters defense
• Barrier-defeating design reliably penetrates heavy clothing and intermediate barriers before expansion
• Extreme expansion profile (6.5–7.5 inch penetration depth) optimized for energy transfer in soft tissue
• 20-round box for convenient storage and practice

Frequently Asked Questions

Is Civic Duty 40 S&W ammunition suitable for home defense and concealed carry?

Yes. The Civic Duty round's design specifically targets defensive scenarios where barrier penetration and controlled expansion matter—common concerns in home-defense and personal-protection contexts. The minimal over-penetration risk is a key safety feature when unintended targets may be behind or beyond the threat.

What does lead-free mean, and why should I care?

Lead-free ammunition uses solid copper projectiles instead of lead cores. This reduces environmental and range-facility contamination and may be required at certain indoor or outdoor ranges. It also eliminates lead exposure during handling and shooting, a health consideration for frequent shooters and those sensitive to lead.

How does Civic Duty expansion compare to traditional bonded hollow points?

According to G2 Research's design, the Civic Duty round's solid copper Trocar geometry expands more reliably and transfers energy more efficiently than typical bonded hollow points, which can over-penetrate or fail to expand consistently. The Civic Duty focuses on extreme expansion (2.5× diameter) and near-total weight retention to maximize tissue damage while staying within safe penetration depths.

Will this ammunition cycle reliably in my 40 S&W handgun?

The 40 S&W Civic Duty round should function in any standard 40 S&W firearm. If you have concerns about function with a specific model—particularly older or less-common platforms—test a small quantity before committing to a full carry load.
