PPU 357 Sig FMJ
PPU 357 Sig 125gr FMJ ammo is solid range fodder, and as hot as anything you're going to find outside exotics/super-light bullets. It is not, however, 1,542 fps out of a duty-length barrel pistol (4 - 5"). It does produce about 1,450 fps, which is about 100 fps hotter than most typical 357 Sig FMJ one finds, so while not screaming fast, it's still up there. It also provides a very satisfying muzzle blast, so there's that... :-)
