PPK ballistics

[LDB415]

Is there anything distinctive about the PPK that allows identifying a recovered bullet as coming from it and no other pistol?

barrel length 83mm, rifling 6 grooves, right-hand twist, one turn in 250mm. Depth of grooves 0.1mm, width of groove 2.55mm

so yes

Ok so when they look at the bullet they'd know it was a PPK and couldn't possibly be any other firearm. I've never studied any of this and thought it might be from gun A, B, C or D. Have they advanced so much they can tell every firearm just from a recovered slug or do they still need to match some of them?

In theory any model with that barrel stats would be listed I dont have the ref to know if any other handguns have that length and all... so maybe maybe not

Maybe Quincy, M.E. could do it, but in real life, I don't think so.
These articles have some good info on forensic analysis of bullets - based on what I read, the answer to your question is "no".

I suspect that a bullet from a PPK would look a lot like bullets from a PP or PPK/S in the same caliber. Or from any other pistol with a similar rifling form.

Abby Sciuto could probably also tell us if the shooter was right or left handed.

We were watching a movie and when they analyzed the bullet from the corpse they claimed it came from a PPK and one suspect had a PPK. I've heard of Glocks being identified by the striations etc. but wasn't sure if there was something like that to absolutely identify a PPK or not. In the same movie the detective is clearing a house with a pistol that is a good 1/2 inch out of battery, clearly visible with the slide back that far exposing that much barrel in the front and overhanging the beavertail by that much at the rear.
