Someone, I believe it was here on PF, mentioned at one point having slugged Beretta barrels, and they're slightly larger than other manufacturers. At that point, pretty much all I had were Beretta, Springfield, and a couple KelTecs in 9x19. Have since added CZ, S&W, Sig, HK, and multiple lengths on Glock. I would love to chrono through them all just for comparison's sake.
