You: Says the man with umpteen 1911s.

Being designed by John Browning means you are 100 years ahead of everything else the day you are born.  No need to be "brought up to date."

No smiley face there because I'm quite serious.  If I weren't concerned about wear on a collectible, I'd carry a 1911 made in 1911 today based on features.  Truly the only thing that has ever needed updating is sights, and that is true about every single pistol of the era and for a long time afterward due to the tactical concept of the pistol in those days.  Sights were not looked at with the same sort of use in mind back then as they are today--of course we all know that.

I could get in my Time Jalopy and go back to perhaps 1912 to meet John Browning and show him my carry gun.  He first want to know why it was silver and I'd explain it was stainless steel--not sure how known that was.  Probably not at all.  I believe Winchester introduced stainless rifle barrels a few decades later.  The fact that it is marked Springfield Armory would be curious to him, but "made in Brazil" would probably piss him off.  I think he'd recognize the pistol without any problem as the only difference otherwise are the Novak sights.  the safety lock is what Colt eventually created as a commercial safety versus the tab-style military safety.  It didn't exist in 1912 but it wouldn't look out of place.  The "A1" changes such as the frame scallops would be there.  Of course I'd explain to him that I'd come from 2018 in my Time Jalopy to explain all those RADICAL changes to my pistol...in other words, no serious changes needed.
