I recently went through 400 rounds of this ammunition on a pistol class taught by Rob Pincus. I was a little concerned that the polymer jacket might not stand up to the heat and blazing sunshine, but I had zero malfunctions, and my weapon did seem less dirty than I was expecting. I can't attest to the friction heat reduction because I couldn't adjust for my weapon being in the sun, but the bottom line is that this ammunition seems to perform as advertised.
Feeds and functions normally even in Walther PPS which can be picky due to high feeding angle. Lightened recoil makes for easy target requisition. Hope to not have to use "real world" but confident to carry.
