For decades, the early 1911's had the nasty habit of firing when dropped onto the ground. Remember the first run of Sig P320's from a couple years ago? The modern millennial gun forum followers nearly wet themselves when a couple youtubers discovered that they could get the P320 to fire when it was dropped "just so" onto a hard surface. They would have curled up into a ball in the corner had someone told them that John Moses Browning's baby did that for decades.
In the 1930's, Colt employee William Swartz solved the problem with his new firing pin block. His system is operated by the grip safety. It was used for a couple years, but the specs from the U.S. Government didn't call for a firing pin block, so the Swartz Safety was dropped.
Decades later, Colt adopted a trigger-operated firing pin block, but the modern millennial forum followers... oops... wait... this was before millennials and forums. Nevertheless, a lot of people didn't like the trigger-operated safety either.
But I've really jumped the tracks here, and better get back to the point before that moderator guy lowers the boom.
People don't like the Swartz Safety because it doesn't work right if not properly adjusted. It blocks both the trigger and the firing pin. If things are out of whack, the gun won't run right.
