I think it's fine to have a debate about gun rights, but my question is about the ergonomics of this modified gun in particular. The trigger is ok at the thumb, but I am concerned about the stability of aim with the barrel between two relatively weak fingers that don't get a lot of practice in holding items still between them. So, speaking as a gun owner, I think it's fair to say that this weapon, or medical device or self-protection device or whatever you want to call it, will need considerable practice to master and probably ongoing training with it to keep the fingers strong enough to steady the thing in an emergency.
Another question that comes up, what caliber is this gun? What is the recoil like? I sure wish it was a 2-handed hold instead of 1.
And lastly, there are a large number of young people with rheumatoid arthritis or other degenerative joint diseases that would be able to use this. So, while made for the elderly, whose hand joints tend to be less mobile than the young, it could be a benefit to quite a large swath of our population.
