Ammo Review: Winchester Elite PDX1 9mm+P Defender 124 grain personal defense ammunition
Winchester Elite PDX1 Defender 9mm +P 124 grain personal defense ammunition is a bonded bullet design intended to succeed against the tough FBI ammunition testing protocol. Without going into top secret details (not really), these tests are intended to examine how ammunition performs in a variety of law enforcement usage scenarios. Do they still expand after passing through barriers like clothing, automobile glass or steel, and common construction materials? Will the bullet achieve adequate penetration after passing through these barriers? Will Jessica still marry Claude after she finds out about his mob connections and previous engagement to the Crown Price of Belgravia?
With the exception of that last question, we know the answers. The FBI was impressed enough with test results of the Winchester PDX1 round to adopt it as their official duty ammunition. While we didn’t replicate the full FBI test protocol, we did tinker around a bit with a similar scenario or two.
Velocity of the Winchester PDX1 9mm +P load was impressive. Winchester rates it at 1,200 feet per second. We measured it with our Shooting Chrony Beta Master placed 15 feet downrange and found results to be better than advertised. Fired from a Glock 17 Generation 4 9mm pistol with a 4.49 inch barrel, we clocked the Winchester PDX1 9mm +P load at an average of 1,264.7 feet per second. Fired from a Springfield Armory EMP 9mm with just a 3 inch barrel, the average velocity measured 1,146.7 feet per second.
Expansion performance was excellent. We fired numerous loads into thoroughly soaked newspaper through 4 layers of light canvas. All rounds expanded perfectly with no sign of hollow point clogging. The largest expansion diameter we measured was .675 inches – nearly double the diameter of an unfired 9mm bullet. While relative to the testing media used, penetration depth was as good as any 9mm load we’ve tested.
Being a bonded bullet design, we noticed no fragmentation or separation of the projectiles and all weighed in with over 98% of their original 124 grain weight.
We found this to be a quality load for personal defense. FBI approved.
