Does anyone have any first hand knowledge of a court case involving a justified self defense shooting that was changed due to the gun being modified?
For me the 3.5# connector and a 6# trigger spring made my groups significantly tighter. I would think that I am less likely to miss my intended target in a self preservation shooting with the modifications.
Depends what you mean by this. I'd recommend reading some of Massad Ayoobs books. He shows some cases where a cocked revolver caused an AD that could have been deemed manslaughter, whereas if it was an intentional shot it would have been justified.
The way the lawyers are going to work it is, if they can get the jury to believe you unintentionally fired, they're going to get you on manslaughter, even if everything else was justified. This is yet another case of, is it worth the risk?
