You heard bullsh**.
Gimme that big, slow bullet--as somebody once said, the best thing about a .45 is that they come "Pre-Expanded".
Regardless of the length of barrel (and 4.4 inches is at least an inch LONGER than what I'd consider a minimum length for a .45), the bullet cuts a path that STARTS OUT a half inch wide whether the hollow point expands or not.
4.4 inches "not long enough for a .45"? A lotta dead bad guys are laughing in their graves at that one...
