I was happy with the performance of the Umarex T4E P2P HDP 50 Gen 2 CO2 Less Lethal Pistol using the 2.7 gram Rubber/Steel Balls for this second Field Test. Energy was very close to the claimed 13 Joules and the average 304 fps I got with this ammo felt snappy and got to the target quickly and sounded like they really hit hard. I do like the higher 15 Joules and 450 fps I got from the lighter 1.6 gram all Rubber Balls, so at this point I would probably recommend sticking with them for the most power and energy down range. Next up I test out the 8 gram all Steel Balls to find out if they are even an option or if they are simply juts to heavy for the Umarex T4E P2P HDP 50 Gen 2 CO2 Less Lethal Pistol.
