First Use Experience
My first experience with the Underwood Ammo 9mm Luger +P 147 Grain Jacketed Hollow Point Nickel Plated Brass Cased Pistol Ammunition
139 39% Off was at an indoor shooting range, where I could control environmental factors and focus solely on the ammunition’s performance.

The recoil was noticeably sharper than standard pressure 9mm rounds, as expected with the +P rating, but it was manageable and didn’t significantly impact follow-up shots. I had no issues with feeding or cycling in either pistol.
Extended Use & Reliability
After several months of consistent use, including multiple range sessions and concealed carry rotation, the Underwood Ammo has proven to be remarkably reliable. I’ve fired approximately 500 rounds, and I have experienced no malfunctions of any kind. The nickel-plated casings have held up well, showing no signs of corrosion or tarnishing despite being stored in a variety of conditions, including humid environments.
The ammunition has maintained its accuracy and consistency over time. Comparing it to my previous carry ammo (Federal HST), the Underwood offers a similar level of precision but appears to provide a more pronounced recoil impulse. Cleaning my firearms after using the Underwood Ammo was straightforward. I have noted no excessive fouling or residue.
