Judging from the high-end finish, and extended mag plate I’d say his 1911 is most likely one of the newer configurations along the lines of a 1991 series 70 or 80 with the firing pin disconnect.
Probably just as safe as any other modern handgun in a similar “condition.”
I guess old habits die hard. My first 1911 was WWII vintage. Second one was a LW Commander made in the 50s. Sadly, they were both lost in a terrible boating accident.
