Sim-X 45ACP Defensecore 72gr Lead Free Hollow Point 20Rnd Handgun Ammo

The Sim-X .45ACP DefenseCore represents a new class of defensive ammunition engineered for everyday carry and professional use. At just 72 grains, this hyper-light projectile leverages Sim-X’s patented SubMass™ synthetic-polymer core to deliver exceptional velocity, reduced recoil, and uncompromising reliability—all without the drawbacks of +P pressures or firearm modification.

Performance-Driven Innovation

• Hyper-Velocity Ballistics: With muzzle velocities exceeding 1825 fps and energy levels over 532 ft-lbs, DefenseCore delivers energy transfer on par with premium defensive ammunition in a lightweight, fast-cycling design.
• Reduced Recoil: SubMass™ technology provides approximately 40% less recoil than traditional 230gr .45ACP loads, enabling faster follow-up shots and improved control under stress.
• Weight Efficiency: Fifty rounds of DefenseCore weigh roughly 53% less than standard .45ACP, a critical advantage for concealed carriers, duty use, or extended field operations.

Advanced Construction

• Synthetic Composite Core: A proprietary viscoplastic material creates superior bore sealing, resulting in consistent velocities and controlled expansion.
• Kinetic-Ceramic Reinforcement: Stronger than lead, this polymer matrix ensures durability, penetration control, and reliable feeding in semi-automatic handguns.
• Lead-Free, Non-Toxic Design: Ideal for environmentally conscious shooters and professional training facilities seeking to reduce exposure and cleanup costs.

Reliability and Safety

Unlike many lightweight, unconventional rounds, DefenseCore requires no +P pressure to achieve its performance. This design advantage reduces firearm wear and enhances compatibility across a wide range of handguns. Quality control measures and cartridge engineering mitigate common competitor issues such as bullet setback and feeding problems.

Market Position

Priced competitively in the premium self-defense category, DefenseCore offers advanced technology and real-world advantages without the risks associated with “gimmick” rounds. While brands like Liberty and G2 Research struggle with inconsistent penetration, and Corbon has documented reliability concerns, Sim-X DefenseCore is built to provide consistent, trustworthy performance.

Sim-X .45ACP DefenseCore 72gr Lead-Free Hollow Point FAQs

What does SUBMASS™ mean?

SUBMASS™ is the lightest ammo category, like the SIM-X 45 ACP RANGECORE™ at 80 grains—almost three times lighter than standard 230-grain rounds.

What is Hyper Velocity?

SIM-X ammo reaches "rifle velocities in a handgun," about twice as fast as typical lead ammo. The 45 ACP DEFENSECORE™ hits 1825+ fps versus 890 fps for standard rounds.

What makes the synthetic-polymer core superior to lead?

It's 100% non-toxic, lead-free, and eco-friendly. It delivers hyper-velocity without high "+P" pressures, reducing firearm wear.

What is SMART BULLET™ TECHNOLOGY?

It ensures nearly 100% penetration control by expanding from base to nose, preventing clogging and giving consistent energy transfer on target.

What is Performance Recoil?

SUBMASS™ projectiles cut recoil by about 50% compared to standard 230-grain ammo, enabling easier handling and quicker, accurate follow-ups.

Is this ammunition suitable for self-defense?

Yes, it's designed for everyday carry with strong terminal performance for stopping power.

What shooting scenarios benefit most from this ammo?

Great for practice due to low recoil, and effective for defensive use needing quick stopping power.

Can this ammo be used in any 45 ACP firearm?

Yes, it works reliably in all standard 45 ACP firearms without modifications.

How is the ammunition packaged?

Sold in boxes of 20 rounds, with bulk case options.

What are the shipping restrictions?
