I shoot a 121 gr 9mm at ~1400 fps in pistol and 115 gr ~1200 fps in rifle (8" barrel) and I am absofrigginglutely sure what works better for distance. 3-point contact with the firearm for the win. So yeah, rifle better than pistol.
As for this stage, a tough one for sure. But then, this was the nationals, right? And if one paid attention to any of the PCC only matches over the years, one would expect at least some shots well beyond the typical pistol presentation. Of the top 10 shooters on this stage (which included Gs, Ms, and one sandbagging junior C shooter ) only 2 had misses. Max had 2 but if you watch his video, he likely traded points for time on that target. He was about 1.7 seconds faster than the stage winner.
Should a whole match be like this stage? Not for USPSA. One target on one stage? Deal with it.
