The FBI has concluded that Alec Baldwin must have fired the gun normally on the set of "Rust" -- which took Halyna Hutchins' life ... this according to a new report.
ABC News published a bombshell story Friday, claiming to have obtained a copy of the forensic analysis report recently completed by the Bureau ... which was examining all facets of the fatal accident in a broader investigation to see if criminal charges are warranted.
Per ABC, citing part of the FBI report, the feds found that the revolver in question -- a single-action .45 Colt caliber F.lli Pietta -- could not have been fired without someone pulling the trigger ... a determination they made after conducting accidental discharge testing.
Unclear if they did this testing with the same exact gun Alec used, or a separate but identical one -- but what the FBI notes in their reports is ... that gun, when working properly, will not release a bullet and primer simultaneously by just fiddling with the hammer alone.
