Your Questions Answered
Is this +P ammunition safe for my firearm?
Check your firearm’s manual. Most modern 9mm handguns rated for +P ammunition can safely fire this load. It is not recommended for use in firearms not explicitly rated for +P pressure. Consult the manufacturer if unsure.
How does it perform compared to standard pressure hollow points?
The +P designation indicates higher chamber pressure, resulting in increased muzzle velocity and energy. The PDX1 bonded bullet is designed for controlled expansion and weight retention, which can be beneficial for defensive scenarios involving intermediate barriers.
Have you tested this ammunition?
Our staff has handled and fired this product. It has demonstrated reliable function with 115gr and 124gr loads. We did note one isolated feeding hiccup with a specific 147gr subsonic load in a particular firearm during testing, but the 124gr +P Defender has performed as expected.
