We know that Beretta pistols have somewhat "slower" barrels compared to other pistols. The reason for this seems to be the larger/wider internal dimensions of the pipe. Has anyone measured the muzzle velocities of other popular pistols such as the G17, G19, CZ-75, P226 and so on, compared to the Beretta 92FS? Does anyone have the measurement results? Also, does the Beretta M9A3 or M9A4 have a higher muzzle velocity since it has a longer barrel?
