Reminds me of shooting my dad's Cobra FS380, where the safety flips down to fire. It falls out of safe if you bump the gun. I imagine an Alien would have a bit more reliability but it still makes me wonder why they designed it like that when there's already a thumbrest/safety literally right below it. It just makes me appreciate the CZ 75 safety even more, where the grip I use to fire the gun is the exact same I use to release the safety if I need to. No fiddling with it or readjusting grip to reach the safety, so flipping back to safe is also instant.
Complications like this seem to explain why people created grip safeties and bladed trigger safeties in the first place, especially for duty/concealed carry.
Edit: Found a photo of the Cobra safety, it's pretty hilariously simple, doesn't seem to have any way to apply tension to keep it from falling in or out of safe.
