The sole reason that we are allowed to have a Co2 method of driving a mechanism that advances a magazine, as in the case of the Steyr LP10 or similar, is that it is NOT a Section 1 firearm, but a sub-6ft lb airgun.
The 'Patriot' pistol or a similar firearm IS a Section 1 firearm.
The words 'self-contained' or 'built-in' added to 'method of loading' by implies a 'self-loading Section 1 firearm'.
The term 'flogging a dead horse' comes to mind here.
I'm done, and you can carry on without my worthless input.
