If I see one more know-nothing compare a Glock to a DA revolver I am going to
Unless that Glock is sporting the usually reviled "NY Trigger," it is not remotely like carrying a DA revolver.
Manual safeties I can take or leave. They ain't rocket science one way or the other.
If you can train yourself keep your boogerhook off of the bangswitch, you can certainly train yourself to ride a thumb safety off during a draw.
Just because certain people perceive themselves to be so panic stricken that they'd forget to take the safety off doesn't mean the whole world is just as handicapped.
My IRL example comes from drilling shipboard with the Ma Deuce. You don't sprint to it and thumb the trigger. You charge it with ammo first. I never forgot to do it the right way every time I had to do it, for drill or for possible keeps.
You fight like you train. Haven't ever failed to swipe off a manual safety pistol doing IDPA and other stress fires. if you find yourself doing that the root cause is laziness or incompetence, it's not the weapon design.
Just like certain people can't handle their liquor and others can't drive cars with manual transmissions, or work the clutch and gear selector of a motorcycle, there are certain people who either cannot handle pistols or who should at best stick to the one type they can actually manage not to screw up with too badly.
A safety-less design probably works better for someone who can't walk and chew gum at the same time.
