Calling STEM nerds! Question about logistics of dual gun suicide timing

[Sourdough]

There's a case study of a person who committed suicide by shooting themselves simultaneously with two guns. How strict of a timing window would this person have to pull off this feat if they were aiming both at their brain? What I mean by timing window, is how close together with the two trigger pulls have to be based on how long it takes the hammer to reach the firing pin. Example: if it takes 10 milliseconds between the trigger pull and the firing pin, you would have about a 10 millisecond window from the first trigger pull to complete the second trigger pull.

Here is the case study https://pubmed.ncbi.nlm.nih.gov/20936481/

Man, I hate when they block the full thing. I also hate how fucking dehumanizingly they write about this person - "the suicide"?! Jesus christ. I love data but scientists are fucking inhuman.

Sadly can't help as I know nothing about gun tech, despite it being a preferred method for me. I imagine it depends on the gun, but using two different kinds of guns would increase the amount of variables, as would aiming at different parts of the body. The brainstem is what you're after so one on each side of that with identical models seems best.

Though obviously this unfortunate soul achieved the result he desired with this MO...

I apologize if I sounded insensitive. Truth be told the reasoning is probably because I'm jealous of this person as messed up as that sounds. Also, here is the full version of the article if you want to read it;
