Description
Cor-Bon engineered the Pow'RBall to handle what other defensive rounds struggle with. If you've got a compact 9mm that's finicky with traditional hollow points, this is the solution. The polymer ball caps a specially designed hollow point cavity, giving it a rounded profile that feeds like ball ammo while keeping all the stopping power you need.
How the Pow'RBall Design Works
The construction is straightforward: a gilding metal jacket wraps a V-shaped lead core topped with a crimped polymer ball. In flight, that polymer tip smooths the aerodynamics and improves ballistics. On impact, the ball delays expansion just long enough to push through several inches of tissue before the jacket peels back into a proper mushroom. It also keeps the hollow point cavity clean if you shoot through heavy clothing, which matters in real defensive scenarios.
Performance from the 9mm +P Load
This runs at +P pressure, delivering 1475 feet per second and 483 foot-pounds of muzzle energy from a 4-inch barrel. The 100-grain bullet is lighter than standard defensive loads, which means you get faster expansion without the heavy recoil of heavier ammunition. That speed matters for quick follow-up shots and keeping your sight picture steady under stress. It's why people using compact platforms have made this their go-to carry round.
Why This Ammo Matters
Feedback from people who shoot these rounds consistently mentions they work through semi-automatic pistols without the jams or nose deformations you sometimes get with conventional hollow points. The design is intentional for short-stroke slides and compact guns, but it runs smooth across full-size platforms too. Brass cased and reloadable, so if you're serious about practice, you can reload the empties.

Frequently Asked Questions
Will Pow'RBall ammo feed reliably in pistols that have trouble with hollow points?
Yes. The polymer ball gives it a full metal jacket-like profile that feeds smoothly in compact and semi-automatic pistols prone to jamming with conventional hollow points. The design was specifically engineered for short-stroke slides, though it works reliably across all 9mm platforms.
How does the polymer tip delay expansion?
When the round hits soft tissue, the polymer ball sits in front of the hollow point cavity and pushes inward during the first few inches of penetration. This delays the expansion until the bullet has driven deep enough to prevent over-penetration. After that initial penetration, the jacket peels back and the V-shaped cavity forces the bullet to expand into a proper mushroom shape.
Is this ammo suitable for practice or just carry?
While designed as a premium defensive load, Pow'RBall works for practice if you're serious about training with carry ammunition. The brass cases are reloadable, so practice shooters often save the empties. Keep in mind this is a +P load and should only be fired in firearms rated for higher pressure 9mm.
What makes Pow'RBall different from standard hollow point ammo?
The polymer-tipped design solves two problems traditional hollow points can't: it feeds as reliably as ball ammo and resists clogging when passing through heavy clothing. Real-world testing shows it penetrates through barriers then expands properly in soft tissue, where standard hollow points sometimes fail to expand if their cavities get plugged with fabric.
