Feds go first.
batteries that can will fail.
I am guessing the average non shooter’s night stand gun is bought, brought to the range ONCE, fired. Put into a drawer and NEVER thought about again. What are the odds that bettery gets changed as required?
The sensor, will need to be 100% clear or ANY dust, dirt, lint.
The hands must be clean (dry?)
The user, under stress, will need to make sure that the finger is in EXACTLY the correct position to unlock.
Does this need to be unlocked for every shot?
No thanks. I’ll take antiquated tech.
A gun needs to be 1000% reliable at all times.
Can the Maker be sued or held liable, if the gun fails to fire? and the owner is injured or killed?
