I'm not talking about learning BJJ. All I'm saying is that defensive shootings often happen within arms length such that you would be unable or unwise to bring the gun up to eye level. All the training I've had has been in that case to shoot from retention, with the gun close to my strong side. In that situation, the facial recognition sensor on the rear of the gun has no line of sight to your face and thus can't work. In other words, this gun is fatally flawed from its conception. Any gun that you can't shoot from a compromised position is a range toy not a defensive tool.
