As was said, I don't think JB's original design had a thumb safety but did have a grip safety?
So Browning did not originate the idea of a cocked and locked 1911. In the military they didn't carry cocked and locked as a general practice but they usually had access to a long gun. But officers and support troops, issued with a 1911, might not have a long gun handy.
Comp shooters pin or tape the grip safety because depending on your hand size/grip technique, it's easy to "miss" the GS and the pistol doesn't fire....this is the reason for beaver tail grip safeties with the bump. JB didn't design this either.
Many carry striker pistols with no "safety" as such, just "safety features"...carrying cocked and locked is just as safe
