Aarondhgram, a slightly belated "Thanks" for reposting the Beretta vs. Bersa picture.
I cringe whenever someone writes that a Series 81 Beretta is a "large" gun, and this description seems to be repeated on this forum with some frequency.
My theory is that they look deceptively large in pictures.
That said, they ARE approximately the same size and weight as a number of more recent double-stack 9mm compacts, and this
is a legitimate critique if you look at these pistols from a simple Firepower vs. Size point of view. However, this criticism can also be leveled at most pistols mentioned in this thread. The Berettas are simply NOT that much larger or heavier than a Bersa Thunder, Walther PPK/S, or Makarov, and I can't fathom where people get the idea that they are.
