Q & A
Is this ammo suitable for all 9mm pistols?
No. +P ammunition generates higher internal pressure. It should only be used in firearms rated by the manufacturer for +P or +P+ use. Most modern service pistols like Glock, SIG, and Smith & Wesson M&P models are +P rated, but always consult your owner’s manual first.
How does the XTP bullet perform compared to other JHPs?
The XTP (eXtreme Terminal Performance) is designed for controlled, reliable expansion across a wide velocity range and through intermediate barriers like heavy clothing. It prioritizes consistent penetration depth over maximum expansion diameter, making it a dependable choice for defensive use.
Is this good for range training?
While it performs flawlessly, +P defensive ammo is more expensive and produces sharper recoil than standard pressure range ammo. It is ideal for function testing your firearm with your chosen defensive load and for periodic training to familiarize yourself with its performance. For high-volume practice, standard pressure FMJ is more cost-effective.
