Corbon Pow'rBall .40 S&W 135 Grain Polymer-Tipped Jacketed Hollow Point (MPN: PB40135)
Concealed carry permit holders, law enforcement officers, and home defense strategists running .40 S&W handguns frequently face two major concerns with conventional defensive rounds: wide-mouth hollow points catching on steep feed ramps, and hollow point cavities clogging with heavy clothing or denim barriers downrange. Corbon engineered their Pow'rBall 135-grain Polymer-Tipped cartridge (MPN: PB40135) specifically to eliminate both vulnerabilities. Purpose-built to provide FMJ-smooth feeding with explosive terminal expansion, this specialized defensive loading ensures absolute cycling reliability and rapid energy transfer across compact and full-size pistols.
At the center of Corbon’s patented Pow'rBall design is a high-lubricity polymer ball securely seated into the mouth of a jacketed lead cavity. This smooth round-nose profile acts like a full metal jacket bullet as it glides up the feed ramp, eliminating nose-hang stovepipes and misfeeds even in tight-tolerance or finicky handguns. Upon impact with soft tissue, the polymer ball is forced rearward into the core, acting as a wedge that mechanically initiates early, aggressive mushrooming. This mechanism ensures wide-diameter expansion through heavy outerwear, leather, and layered fabrics without the risk of cavity clogging.
Out on the range or in high-stress personal defense situations, expect crisp ignition, flat trajectories, and reduced muzzle flip compared to standard heavy 180-grain duty loads. Driving its lightweight 135-grain bullet at a blistering muzzle velocity of approximately 1,325 FPS, this loading produces over 525 ft-lbs of kinetic energy, generating massive hydrostatic shock while keeping recoil manageable for lightning-fast follow-up shots. Corbon loads these rounds into factory-fresh, heavy-walled reloadable brass cases charged with low-flash propellants and non-corrosive boxer primers, protecting night-adapted vision during low-light defense encounters.
Armorer Bench Notes & Technical Maintenance Guidance
Shipping Restrictions: Ammunition sales are strictly regulated. Check all state and local laws prior to ordering. Cannot ship to PO Boxes, APO/FPO addresses, or internationally. Must ship via ORM-D / Hazardous Ground transport.
Armorer Tip: The polymer ball tip creates an overall cartridge contour identical to standard round-nose ball ammo, making it an outstanding defensive choice for older or match-grade .40 S&W pistols with narrow, steep, or unpolished feed ramps (such as early 1911 conversions or Browning Hi-Power patterns). Check your magazine springs annually and keep chamber throats free of carbon fouling to maintain seamless feeding under rapid-fire conditions.
Key Features
- Patented Polymer Ball Cap: Creates a smooth round-nose profile that guarantees FMJ-style feeding reliability across steep ramps.
- Clog-Proof Terminal Expansion: The polymer sphere drives backward upon impact to force reliable hydraulic expansion through heavy clothing.
- High-Velocity 1,325 FPS Profile: Delivers over 525 ft-lbs of kinetic energy for devastating hydrostatic energy dump and controlled penetration.
- Reduced Snappy Recoil: Lightweight 135-grain bullet reduces felt recoil and muzzle climb compared to heavy 180-grain defensive loads.
- Low-Flash Defensive Propellants: Custom powder formulation suppresses blinding muzzle flash to protect night-adjusted vision.
