Barrel forensics (ok it's a movie)
Saw the tail end of a movie, where the suspect happily surrendered his weapon (same caliber as the murder weapon) to the police for forensics testing, and it came back a match for the caliber but negative for his gun....
But he did it with that gun as we found out in the end proudly displaying the gun to a friend, but you don't know how.
I'm guessing he either swapped the barrel (can a glock / S&W / ?? barrel fit in some other brand ?), or possibly sanded / slightly machined the inside of the barrel after the murder.
Any hints?
