According to Wikipedia it was a Smith & Wesson Bodyguard.

S&W model 49 was introduced in 1959. I have been shooting small frame Smiths for over 50 years snd that picture looks right to me.
I recall watching this on the news. Was evening news sitting in living room with mom and dad, was during Tet (1968) There was no warning on the graphic nature of the segment. Hard to forget blood pulsing out of his head as he fell to ground, as it continued to pour onto the street. At that point the war was lost in my opinion, regardless of the victories our troops had.
