I've done enough carrying, shooting, and training to know. These "smart guns" might attract a few new gun owners, but nobody who is serious about guns will buy one.
It's all about reliability. I carry a Glock because it just works, with an incredibly tiny chance of malfunctions. My ex-wife preferred a huge 8-shot .357 Magnum revolver, because she didn't want to train to clear malfunctions.
Seriously, my carry gun is a Glock 19, my rifle is a M1A, and my shotgun is a Saiga 12... you're not selling me anything less reliable, which any "smart gun" would surely be.
