Are Ballistic Forensics Useless?

[NYReload]

I was asking some people on this forum about the possible risk of buying a used guns if that gun was used in a crime.

Now I got to thinking after someone mentioned something, what is stopping a person who shot another person with say a Glock from simply removing the firing pin and barrel and replacing both?

Hell a person afraid of legal ramifications of a self defense shooting could easily have extra barrels and firing pins at home and swap them out if they want to. the barrela n d pin can be destroyed and the crime could remain unsolved.

Am I missing something?

They'd also need to replace the breech block.

Because something does not have value in some situations, does not eliminate its value in other situations.

Criminals are probably not the smartest people, but I don't think they would sell a firearm that had been used in a crime since it could be traced back to him easier (assuming the transfer was legal). They are more likely to get rid of the gun. You should keep a record of when you purchase the firearm (the copy you get from the dealer) since that is your proof that the gun was not in your possession at the time of a possible crime the gun was used in by the previous owner.

If the BG's start using frangible bullets forensics go right out the window. No bullet to test or compare to any weapon it's used in.

In a semi auto the extractor would also have to be replaced.

No. Forensic ballistics to define. Useless? No.
