yeah, right...you trust your life to every little part and screw in the weapon and in someone else who manufactured the live round in your chamber.
you can replace the battery every month and test the new one before you install in....for a couple of bucks.
yeah, right...Why not load up a revolver, place it in my nightstand and feel comfortable that in 40 years it will still fire every round.
I say this because in the mid 70s I found a revolver (S&W M1917) in my grandmother's nightstand. She said she put it there when my grandfather went to fight WWII in 1943 and never moved it since then. I took the revolver out to the range, shot the bullets that were in it, fired about 30 more rounds, cleaned it, lubricated it, refilled it with modern hollow points bullets, and put it back in her night stand. In the mid 90s, my grandmother died. I took the pistol home with me and repeated what I did in the mid 70s. It sleeps in my nightstand now. I have another S&W 1917 for target practice, so there is no need to wake my grandmother's pistol up.
And then you are still relying on a battery, and delicate electronics, that will end up being made in China once the ball gets rolling on smartgun legislation and laws. Non-electronically enhanced guns will NEVER have an electronic failure.
What is your point?
