I imagine some firearm sales are for more recreational purposes.
Basic fire arms etiquette is to treat any firearm as loaded and ready to fire unless it's been explicitly cleared.
If you do not use guns for self defense then keeping them clear and keeping ammo separate is much easier and safer.
Any type of safety can fail and relying on it is just how you get some of these accidents.
The iP1, in particular, is also weird simply because it doesn't seem to know what it wants to be. It's not a defensive handgun, the caliber is totally inadequate. But barely anybody uses a compact pistol like this for recreation.
They say "just a few inches" which implies less than a foot. That's not going to work for law enforcement or anyone really.
Honestly sounds like they didn't think too hard about real world usage. That describes most handgun manufacturers though and isn't strictly limited to smart gun manufacturers.
People practice one handed reloads and failure drills.
Even in competition you are regularly required to alternate no strong hand only and weak hand only so it isn't possible to put the watch on the right hand. Proper technique also has you anchoring the unused arm.
