Beretta M9/92F, or some variation or facsimile thereof.
By the by, is *excessively long name* a character in a manga serial or just a sort of Comic Aun "mascot" or cover art? I was going to make a quick wiki entry, but I haven't found any information as to that respect.
Perhaps "Poplip" is a reference to the slide failures experienced with "hot" 9mm loads in the M9. "You're not really a SEAL until you've tasted Italian steel."
