Research the Harold Fish event in AZ.
That incident comes up often in gun/tactics forums.
Fish, a retired teacher, used a SAO type 1911a1 Caspian frame 10mm.
The prosecutors put up a "expert" who testified how no sworn US law enforcement agency used a single action 10mm sidearm with 10mm Hydra-Shok rounds.
A female juror later told a NBC news crew; "I don't know why he(Fish) had to use those hollowpoints or carry a 10mm pistol."
The juror also said: "I don't know a lot about guns."
In a recent court case in my area, the jurors in a homicide case asked to review the murder weapon; a S&W .357magnum Sc J frame revolver. They convicted the defendant.
Author and legal use of force expert, Massad Ayoob(who also chaired legal & LE panels on use of force topics) has put out a few articles about brands/labels too.
