Its not just the 1911s. The berettas, USP etc have external manual safety switches. I love the look of the glocks. I love the fact they use polymers too as the outer shell is more resilient than metal sometimes and won't need re-bluing/blackening of scratches like steel or aluminum would.

But I never thought a trigger safety, right at the trigger, is much of a safety at all. Basically its "don't pull the trigger then it wont go off", well duh. What if something gets snagged in the trigger guard area and depresses the trigger safety like a finger would? Its just inherently not safe.

Actually as for fast draw and fire, the same can be said about good muscle memory and training of a firearm to remember to disable the safety in the case of firearms with safety. Also, a lot of guns without manual safety are often kept without a round in the chamber as the 'safety in place of a manual safety switch', so you'd have to rack the slide to load a round in chamber anyway. More time is spent racking a slide than switching a manual safety off.

I think having a double action and heavy trigger pull, then added with a manual safety switch, is probably the most practical. You can get a round off by pressing hard in double action mode in quick draw and react situations. So you can keep a round in the chamber and maybe even leave the safety off. But with glocks it all comes down to trigger movement whether or not a round goes off. And if people accidentally snag the trigger with a stick, pen, lipstick etc - and it depresses the trigger, then you get accidental fire.
