Description
Cor-Bon's 185-grain hollow point for 45 ACP +P is built around what the company does best: high velocity combined with premium component design. This load runs at 1150 feet per second, which puts it considerably ahead of standard pressure offerings. The lighter grain weight paired with the velocity advantage means rapid bullet expansion on target while maintaining the penetration depth you need in a serious defensive round.
What Makes the 45 ACP +P 185gr JHP Design Work
The bullet itself features internal and external serrations along with a soft lead cavity, all engineered to expand consistently when fired into typical barriers. Field testing shows an average penetration depth of 9 to 15 inches in ballistic gelatin, which lands it solidly in the practical range for defensive use. The combination of velocity and controlled expansion is where Cor-Bon built its reputation, and this load is a direct product of that approach.
Building the Cor-Bon Round
You're getting brass cases that are reloadable if you want to stretch your investment on practice rounds. The ammunition uses non-corrosive Boxer primers and is loaded at their South Dakota manufacturing facility. Each box holds 20 rounds, and cases are sold in 25-box cases of 500 rounds if you want to stock up for regular training.
One thing worth noting: this is a +P load, which means higher pressure than standard 45 ACP. Your firearm needs to be rated for +P ammunition before you shoot it. If you're working with an older gun or something you're unsure about, check the manual or contact the manufacturer. The increased velocity and power come from that hot load, so make sure your platform handles it.

Frequently Asked Questions
Will this +P ammunition work in my 45 ACP firearm?
Not all 45 ACP firearms are rated for +P ammunition due to the higher pressure load. Before using these rounds, check your firearm's manual or contact the manufacturer to confirm it's rated for 45 ACP +P. Older firearms or guns of questionable quality may not be safe with this load. Never assume a 45 ACP is rated for +P without verification.
How does this 185-grain load compare to heavier grain options?
The 185-grain weight at this velocity gives you faster expansion than heavier bullets while maintaining solid penetration depth. For compact or shorter-barrel pistols, this grain weight is often preferred because it generates higher velocity. For full-size 1911s and service-size guns, some prefer heavier 230-grain loads, but the 185-grain hits a practical middle ground that works well across most platforms.
Can I reload these brass cases?
Yes. Cor-Bon loads these in reloadable brass cases with Boxer primers, so you can reload them if you want to manage your ammunition costs for practice. This makes them popular among shooters who do frequent training and want to recycle brass.
What's the practical use for this ammunition?
This is a defensive load purpose-built for personal protection and self-defense. The high velocity combined with the hollow point design is meant to stop a threat effectively. Because of the +P pressure and recoil characteristics, extensive practice is important before relying on it for serious use.
