First Use Experience
My initial testing grounds for this Underwood Ammo .40 S&W were the familiar environs of my local indoor shooting range, a controlled setting perfect for evaluating basic function and accuracy. I loaded a full magazine into my preferred .40 S&W pistol and began a series of controlled firing drills. The immediate sensation was one of smooth cycling through the action; the nickel-plated brass fed flawlessly from the magazine and ejected cleanly without any hangups.
Underwood Ammo’s claim of flash-suppressed powder was immediately apparent. Even in the artificially lit range, there was a noticeable reduction in muzzle flash compared to some other ammunition I’ve used. This is a crucial feature for low-light conditions, and while the range isn’t a true low-light scenario, it provided a tangible demonstration of this advertised benefit. Accuracy was also quite impressive from the outset, with tight groupings on the target at 15 yards, suggesting a high degree of consistency in the ammunition’s manufacturing.
Extended Use & Reliability
Following that initial range day, I’ve since put these rounds through a considerably larger volume of fire, including some informal plinking sessions outdoors and dedicated drills focused on rapid-fire scenarios. The reliability has remained consistently high. I’ve experienced zero malfunctions – no stovepipes, no feeding issues, no primer failures – across several hundred rounds fired from different firearms chambered in .40 S&W. This consistent performance is a critical factor for any ammunition I would consider for more serious purposes.
Durability, in the context of ammunition, translates to consistent performance over time and through various environmental exposures. These nickel-plated casings have proven remarkably resistant to tarnish, even after being stored in my range bag for extended periods where they’ve been exposed to ambient humidity. Cleaning after range sessions has also been notably easier; the nickel plating seems to shed fouling more readily than traditional brass, making the cleanup process quicker and less labor-intensive. Compared to some of the more budget-friendly bulk options I’ve used in the past, this Underwood Ammo truly stands out in terms of its sustained quality and ease of maintenance.
Breaking Down the Features of **Underwood Ammo .40 S&W 135 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition

Specifications
This ammunition features a 135-grain Jacketed Hollow Point (JHP) projectile, a weight that strikes a good balance for the .40 S&W cartridge, aiming for deep penetration and reliable expansion. The casing is Nickel-Plated Brass, a significant choice that enhances feeding reliability in semi-automatic firearms by providing a slicker surface, and offers superior corrosion resistance compared to untreated brass. This plating also makes for easier visual inspection and cleanup, as it resists tarnishing.
The Boxer Primer configuration means these cases are reloadable, a point of consideration for handloaders seeking to maximize the value of their spent casings. Underwood Ammo also specifies the use of flash-suppressed powders, a critical feature for defensive use in low-light conditions to prevent temporary blindness from excessive muzzle flash. The ammunition is described as new production, ensuring it hasn’t been reloaded or subjected to questionable remanufacturing processes, and is non-corrosive, a standard but vital specification for firearm longevity.
These specifications translate directly into practical benefits. The 135-grain JHP design is engineered for controlled expansion upon impact, maximizing energy transfer for defensive or hunting applications. The nickel-plated brass casings contribute to a smoother firearm cycling, which is particularly beneficial in semi-automatic pistols where reliable feeding is paramount, especially under stress. Compared to standard brass casings, the nickel plating offers a noticeable advantage in slickness and corrosion resistance, meaning your ammunition will look and function well even after prolonged storage or exposure to the elements. The flash-suppressed powder is a subtle but important detail that directly impacts shooter visibility and confidence in critical situations.
Performance & Functionality
In terms of its primary function, the Underwood Ammo .40 S&W 135 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition
220 45% Off delivers exceptionally well. The expansion characteristics of the JHP bullet, combined with the velocity generated by Underwood’s proprietary load, result in impressive terminal performance. My testing, which involved simulated impact targets, showed consistent and significant expansion of the hollow point, indicating effective energy transfer. Accuracy, as mentioned, is a strong suit; even at extended range (25 yards), the groupings remained tight and predictable, a testament to the quality of the projectiles and the precision of the loading process.
The strengths of this ammunition lie in its robust energy, reliable expansion, and consistent accuracy. It feels like a premium defensive load, providing confidence that it will perform as intended when it matters most. However, if I were to identify a minor area for potential improvement, it would be the overall muzzle blast and recoil impulse. While not excessively harsh for a .40 S&W, it is noticeably snappier than some lighter-profile rounds, though this is inherent to high-performance loads. Considering the price point and its intended application, the overall performance far exceeds expectations.
Design & Ergonomics
The design of this ammunition is focused on function and reliability, and this is evident in its construction. The nickel-plated brass casing is not just for show; it contributes significantly to the smooth feeding characteristics essential for semi-automatic handguns. The jacketed hollow point design is precisely manufactured to promote reliable expansion without fragmentation. The overall finish is clean and uniform across all rounds, indicating rigorous quality control during production.
From a usability standpoint, the ammunition is straightforward: load it into your magazine, and it performs its job. There is no learning curve; the Boxer primers are standard, and the nickel-plated brass feeds flawlessly. The tactile feel of the casing is smooth, and the weight of each round is consistent, providing a reassuring heft. The flash-suppressed powder is a subtle but impactful design choice, enhancing the shooter’s experience and safety, particularly in dimly lit environments.
Durability & Maintenance
Ammunition, by its nature, has a defined shelf life, but the build quality of these Underwood rounds suggests excellent long-term stability. The nickel-plated brass casing is a key factor here, offering superior resistance to corrosion and tarnishing compared to standard brass. This means that even after extended periods of storage, the casings will remain clean and function smoothly. I have personally experienced ammunition from other manufacturers that tarnished significantly, leading to feeding issues; these Underwood rounds have shown no such degradation.
Maintenance for ammunition is primarily about proper storage: keeping it dry and within a reasonable temperature range. The durable construction of this Underwood Ammo means it is less susceptible to environmental damage. If any failures were to occur, they would likely stem from the firearm itself rather than the ammunition, given the consistent quality I’ve observed. Any potential concerns would be related to the standard considerations for any ammunition – ensuring it’s stored correctly and used within its intended lifespan.
Accessories and Customization Options
For ammunition, the concept of “accessories” is generally limited to packaging and related shooting gear. This particular offering comes in a standard 20-round box, which is a convenient size for range trips or for stocking a defensive carry firearm. The nickel-plated brass casings, as mentioned, are reloadable, which can be considered a form of “customization” for those who engage in handloading, allowing for reuse and potential cost savings over time.
While there are no direct accessories included with the ammunition itself, its compatibility with standard magazines for .40 S&W firearms is excellent. The Boxer Primer system is a universal standard that facilitates reloading efforts. For optimal use of this high-performance ammunition, pairing it with reliable magazines that are known to function well with JHP rounds is advisable. Clean and well-maintained firearms are also paramount, as even the best ammunition can encounter issues in a poorly functioning gun.
