Unless you are just using your handgun for sport, this sort of defeats the purpose of having one for defense. And as long as you are just using it for sport, why not just have a 2-key lock, and you give the second key to your trusted buddy.

At any rate, I applaud any efforts to curb handgun deaths. I personally think handgun purchases should come with a free suicide prevention pamphlet or similar. I've long argued that if people really cared specifically about gun deaths, handguns should be the first and primary target, not "ghost guns" and bump stocks and other rarely-used (but scary sounding) accessories.

Handguns aren't particularly useful in war either compared to rifles, are easily concealable, and are just all around bad news. I think most of America's "gun epidemic" could be solved just by cracking down exclusively on handguns (for both civilians and police) and not bothering with rifles. It's counter-intuitive because a lot of mass shooters use rifles, but if you look at the numbers, the total number of people that die from mass shootings (and rifles in general) is very small, especially when compared to handgun deaths.
