Unfortunately, LUCC ( locked unloaded concealed carry) is an ineffective means of self defense. I hold a CCW permit and carry daily, and must thus state that even with a loaded pistol on my hip in certain cases I'd be unable to defend myself. LUCC presents a problem because any situation which allows you mother enough time to unlock, load, chamber, and shoot is enough time to withdraw and dial 911.
This point is important considering that after any live fire defensive incident the citizen WILL have to justify their actions in court.
The more prohibitions you have, the less virtuous people will be.
The more subsidies you have, the less self reliant people will be.
-Lao-Tzu, Tau Te Ching. 479 BCE
The 1911 may have been in wars for 100 years, but Masetro Bartolomeo Beretta was arming the world 400 years before John Browning was ever a wet dream.
