G42 needs full power ammo.
Define full power. How when buying factory ammo do I tell the difference?

It's a relative term (otherwise somewhat meaningless), but in the context of the G42 what "full power" is referring to is a loading that generates at least 200 lbs of energy at the muzzle (4"brl.). This doesn't translate directly to feet per sec., but in general will usually mean a loading that reaches at least 950fps from a 4" barrel.
Some loads that are very close to the 200 lb. threshold are: UMC/Rem 95gr., Winnie White Box 95gr. Fiocchi's 90gr. JHP is right about at that power level with a fps of about 1,000fps (4"). There are many others.
It's worth owning a copy of this:
Ammo & Ballistics 5: Ballistic Data out to 1,000 Yards for over 190 Calibers and over 2,600 Different Loads, Includes Data on All Factory Centerfire and Rimfire Cartridges for All Rifles and Handguns
It's a pretty handy reference and will help you sum up almost every commercially loaded cartridge out there.
Interestingly, the "hottest" .380ACP loadings (such as some of the Buffalo Bore brand cartridges) are turning out to be a little bit too energetic for reliable use in the G42. With those, the G42 will sometimes lock the slide back on a still loaded magazine.
