MP's mention disabled shooters in the debate as is the NRA. And is just one of many valid objections.
Your how many are affected question can be answered as, every single disabled person. Who may have wanted to shoot but could not because these types of rife are not available to them.
I guarantee a type of firearm you own was used by the IRA so what's to stop them banning that as its was a terrorist weapon.
thin end of the wedge.
My MP is pro shooting and will be attending a club shoot so will get to use a nasty black leaver release so he can form a opinion based on real evidence.
At least I am doing something, doing nothing is the nimby way.
