For years, I’ve preached the gospel of knowing your gear, and that extends far beyond the firearm itself. Ammunition is arguably the most crucial component, the link between your training, your equipment, and the intended outcome. That’s why I was intrigued by the Underwood Ammo 9mm Luger +P 124 Grain Full Metal Jacket Nickel Plated Brass Cased Pistol Ammunition
136 24% Off, promising a potent blend of performance and reliability.
My quest for this particular ammunition stemmed from a growing need for a consistent, high-performance training round that could also pull double duty in a self-defense scenario. I wanted something with a bit more punch than standard 9mm, while still maintaining manageable recoil and accuracy for extended practice sessions.
Opening the box, the first thing that struck me was the visual appeal of the nickel-plated brass casings. They exuded a sense of quality and attention to detail that isn’t always present in range ammunition. Compared to the typical dull brass of other FMJ rounds, the Underwood Ammo’s gleaming casings instilled a sense of confidence.
I’ve used similar 9mm +P FMJ rounds from companies like Federal and Winchester, but what drew me to Underwood Ammo was their reputation for pushing the envelope in terms of velocity and energy. Many online sources showed independent ballistic tests that placed them well above their competitors. I wanted to see if it lived up to the hype.
Initially, I was excited to get this ammo to the range. The promise of increased velocity and energy in a standard FMJ package, coupled with the visual appeal of the nickel-plated casings, definitely piqued my interest.

First Use Experience
I tested the Underwood Ammo 9mm Luger +P 124 Grain Full Metal Jacket Nickel Plated Brass Cased Pistol Ammunition
136 24% Off at my local outdoor shooting range. The weather was typical for a late summer afternoon – hot and humid, with a slight breeze. I ran the ammunition through a Glock 19, a Sig Sauer P320, and a Smith & Wesson M&P Shield, all reliable platforms that I use regularly.
The performance was immediately noticeable. The +P designation was evident in the increased recoil impulse, but it remained manageable in all three pistols. Accuracy was consistent across all platforms, with tight groupings at 10 and 15 yards.
There were no malfunctions during the first 200 rounds fired. The ammunition fed smoothly, extracted cleanly, and ignited reliably in all three firearms.
Extended Use & Reliability
After several months and approximately 1000 rounds, the Underwood Ammo has proven to be remarkably consistent and reliable. There have been zero malfunctions of any kind. The nickel-plated casings still look relatively clean, resisting tarnishing better than standard brass.
Even after being stored in a range bag for extended periods, the ammunition continued to perform flawlessly. Regular cleaning of my firearms after each range session has kept them in top condition. So far, I have found that the ammunition is not corrosive and that standard cleaning procedures work well.
Compared to other range ammunition I’ve used, the Underwood Ammo definitely delivers on its promise of increased performance. The tighter groupings and consistent velocities make it a worthwhile upgrade for training and self-defense.

Specifications
The Underwood Ammo 9mm Luger +P 124 Grain Full Metal Jacket Nickel Plated Brass Cased Pistol Ammunition
136 24% Off boasts several key specifications that contribute to its performance. It is a 9mm Luger +P cartridge, meaning it is loaded to a higher pressure than standard 9mm rounds, resulting in increased velocity and energy. This higher pressure demands a firearm rated for +P ammunition.
The bullet is a 124-grain Full Metal Jacket (FMJ), a common projectile type known for its reliable feeding and penetration. The cartridge case is made of nickel-plated brass, which offers enhanced corrosion resistance and improved feeding reliability. The nickel plating makes it easier to load into magazines and chambers.
According to Underwood Ammo, the ammunition has a muzzle velocity of 1225 ft/s to 1350 ft/s, depending on the firearm used. This translates to a muzzle energy of 502 ft-lbs. It is packaged in boxes of 50 rounds.
These specifications matter because they directly impact the ammunition’s performance in terms of accuracy, recoil, and terminal ballistics. The +P loading provides a significant boost in energy compared to standard 9mm, making it a more effective self-defense round. The 124-grain FMJ bullet offers a good balance between penetration and expansion.
