They felt solid in hand, and the uniformity of the rounds was visually apparent. It wasn’t the cheapest option available, but the promise of premium components and meticulous loading practices from Underwood Ammo piqued my interest.
I had briefly considered other high-pressure loads from more mainstream manufacturers, but they often lacked the specific features or reputation for consistency that Underwood Ammo seemed to possess. The immediate reaction upon receiving this ammunition was a distinct sense of curiosity mixed with a quiet confidence that I had potentially found a new benchmark for my 9mm needs. The 136 24% Off sale also made this premium option considerably more accessible.

136 24% Off** to the Test
First Use Experience
My initial testing took place at my local indoor range, a controlled environment where I could focus solely on the ammunition’s performance. I loaded up my preferred 9mm pistol, a reliable striker-fired model known for its accuracy, and began a series of controlled fire drills. The primary objective was to assess feeding reliability and the feel of the recoil impulse, especially with the +P designation.
The ammunition cycled through my firearm flawlessly from the very first round. There were no feeding failures, no stovepipes, and no issues with ejection. The nickel-plated brass casings fed smoothly from the magazine, a testament to their precise dimensions and finish. The recoil was noticeably firmer than standard 9mm loads, as expected from a +P round, but it was a manageable and consistent push, rather than a sharp, jarring kick.
One of the immediate surprises was the clean burn of the powder. There was minimal muzzle flash, even under the dimmer indoor lighting conditions, suggesting the use of effective flash-suppressed powders. This attention to powder quality is something I always appreciate, as it contributes to a more pleasant shooting experience and less fouling on the firearm’s internals.
Extended Use & Reliability
Over several months, I’ve cycled through multiple boxes of this ammunition, integrating it into both my regular range practice and some more rigorous training scenarios. I’ve used it in various conditions, including a few days out in damp, cool weather, and I’ve yet to experience a single malfunction. The 124 grain Full Metal Jacket (FMJ) projectiles have proven remarkably consistent.
The durability of the nickel-plated brass casings is also worth noting. After extraction, they show minimal signs of stress or deformation. I’ve reloaded some of these cases successfully, which speaks to their robust construction and ability to withstand multiple firing cycles. Cleaning my firearm after using this ammunition has been straightforward; the powder residue is minimal and easily managed.
When compared to other +P loads I’ve used in the past, this Underwood Ammo stands out. It offers a superior balance of power and shootability. While some other brands can feel overly aggressive or inconsistent, this particular load provides a predictable and effective performance that instills confidence. Budget options, while cheaper, simply do not offer the same level of refinement or consistent energy delivery.
