Why do you assume he spent “all that cash on 9mm”?
The explosive sales of Beretta 92FS is a result of his use of one in “Lethal Weapon”. Beretta may have gifted him one.
Gibson is worth over $500 million, which not only means he can afford to buy whatever he likes, but that he doesn’t likely have a small dick problem requiring a bigger calibar pistol.
Mel told you all about his weapon collections, eh? Got one stashed in yer undie drawer, maybe?

Silly me- I thought that it was because it was adopted by the US Armed Forces in 1985 as the main sidearm, replacing the .45 1911A1.
