It was probably six from a semi-automatic. The intended victims were seated inside their car, making it difficult to pivot or turn; the driver would have had to extend his right hand across his chest to fire. Given fear of imminent danger, getting off six rounds pop-pop-pop-pop-pop-pop, would be much easier with a Glock than a revolver.
Anyway, they’re safe and that’s good. Someone wrote,
“Why six times?” “Because he was still armed and kept trying to get up.”

Cause the 7th round misfired.
