PS, John am I right in understanding that the trigger guard is also the trigger spring? If so, I find this truly revolutionary. So when you pull the trigger, you are also bending the guard and the resistance provided by the trigger/sear on the piston rod bent is only part of the resistance you feel when you fire the gun?
Come to think of it, I have an issue with this. If I have understood the design correctly, the trigger guard acts directly on the sear. Initially I thought that was very neat, on reflection I think it’s conceptually flawed from a safety angle.

Also although I like the separate cocking lever, from a manufacturing point of view the design of all other pistols of this type that use the trigger guard is surely better.

The air guide holes at the rear of the piston are also unnecessary. In fact isn’t that whole part unnecessary, save perhaps to eliminate dead volume

Although I still agree a lot of thought went into this parts of it now seem overthought
