Three serial numbers on a firearm now?

[230RN]

Firing pins (at least for 1911s) are cheap, and easy to change.

And don't forget the extractor scratches and ejection port dents on the fired cases.  I'm not 100% sure I believe that, but I suppose it's a possibility.

And after all, it's just good manners to police your brass.

Back in 1993 Tom Clancy wrote Without Remorse,  and Kelly drilled and tapped holes to screw a catch bag over the ejection port of his 1911 when he converted it to an assassin pistol. That part of the story was set in the 70's.

If you are doing sketchy *expletive deleted*it, leave as little as possible for the CSI guys to mull over.  (Although in reality,  it seems like if you aren't obvious, and don't post video to the web, they don't really find you)

Did he recommend getting rid of all, repeat all, ammunition of the type and brand that was used, and run a oouple of rounds of fresh new different brand ammo through that new barrel?  Don't remember where I read that..

Uh oh - you mean maybe I shouldn't post video on YouTube, X, Instagram, and TikTok if I ever do something illegal? I'll make a note.

It seems every time you turn around there's a news story of some idiot criminal posting his stuff on the internet - a few years ago it was high schoolers posting film of themselves smashing mailboxes, and I've seen video of a guy in a supercar running at 3x the legal limit on the highway. Last week it was cellphone video of a couple of thugs in a car deliberately running over and killing a bicyclist - an outright murder they committed, just for kicks. And posted on line.

It helps the cops catch bad guys when lot of criminals really are dumb.

As for the Tom Clancy novel stuff - if you're a contract killer or other assassin worried about a ballistic match, there are some pretty simple ways to change the ballistic "fingerprint" of any gun. But as a "professional" you should already be prepared to ditch/destroy the weapon entirely.
