I was told by a good source years ago that the Israels used a 45acp mac 10 instead of the Uzi 9 mm because the slower moving, heavy hitting 45 would be less likely to pass through the enemy and kill a hostage.
I’ve never been able to confirm it officially. I guess the Israels didn’t want to diminish their own weapon by disclosing this.
According to a friend who is former IDF they used Uzi’s with hollow points. He was highly offended that I even had the nerve to ask him if the MAC rumor was true. That said I am pretty sure that a few of the commandos carried AK47’s.
