If it's a good shoot - why are you on trial?
There is a large body of research on what influences juries. Weapons issues have been shown to influence mock juries.
There is no way to know what goes on in a specific trial. Prosecutors do make it a point of displaying and exaggerating the weapon. If they didn't, would their presentation be less effective? Can't tell in that specific case as we don't have alternate realities. Thus, the simulations.
Take it or leave it. You will have the jail time fun.
