Typically the edge goes to the rotating barrel. This is what made the PX4 such a nice shooter. Ironically, the new PX4 sub-compact, which does not have the rotating barrel, is a BETTER shooter than the standard PX4. Beretta just flared the end of the PX4 SC's barrel for a nice tight fit.
i keep hearing this, but i NEED to judge for myself!
i have many many pistols, but my px4 is absolutely my go-to gun
i also shoot in a small local pistol league weekly, i use my px4 for that too
accuracy wise, the rotating barrel is incredibly tight which i'm sure helps greatly
