The description makes it sound like if you are firing weak hand (or strong hand) you might be outside the range of the watch?

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.

Anecdotal story: I have a friend who works for the Indiana State Police and was on the committee to procure new service pistols. In every category, the Springfield XD won. Problem was, it had a grip safety. ISP requirements dictate that no safeties could interfere with operation when needed, as they may have to fire in a compromising situation if in a struggle, for example. Not being able to firmly grip the pistol and engage the safety was a non-starter. When drawn, the firearm had to fire if the trigger was pulled every time. So Glock it was, which only has a trigger safety.

The intention clearly seems to be for the watch to be worn on the same arm that you hold the gun with.

It's not safe to assume the arm that has the watch will be available to operate gun.

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.
