The 147 is listed at 1250 by one seller, but here is a different link. Never had an issue with their 9mm, but their .380 is not so good.

Does anyone know the specifications for this ammo (Perfecta PF912400)? Specifically I'm trying to find its muzzle velocity so I can calculate its energy and power factor.
I can't find anything with any of my web searches.
The closest data that I've found is for Fiocchi (the manufacturer of Perfecta). The muzzle velocity for their 124 grain FMJ is 1180 fps, but I haven't found anything specific for Perfecta.
I deduced that it is somewhere between 1100 -1250 fps. Glocks shoot any 9mm so it's never been an issue for me. When you lower caliber things can get finicky in a semi.
