In my opinion, tests like these prove that the only difference between the different pistol rounds as far as how effective they are is cost, recoil and magazine capacity. Though that is a pretty seriously weak 9mm load they reference here. That bullet could be going quite a bit faster.
No, that's not that slow. Even most +P 9mm 124 grainers are only going to hit low 1200s. Win Ranger 127 +P+ is like 1270 ish out of a Glock 19.
Bear in mind that most 124 gr Factory "practice" loads chrono at like low 1100s or even 1050 FPS or so.
