Says the guy who lives under the "rule" of a monarchy with no real power. All your royal family does is cost you money to no real purpose. Guns are not pointless - they exist for varied purposes from hunting to self defense to plain recreation. (Ever shot one? It's fun, at least in the context of clay pigeons or paper targets.)
To the person who said guns for protection exist only to protect from others with guns, I have to say that's not true. You find yourself at a distinct advantage vs an attacker with a knife or other non-gun weapon if you have a gun, whereas you'd be mostly helpless unarmed. (This argument presumes you're not a black belt in some martial art, etc.) Also, the police can't be everywhere at once - carrying a gun is simply a decision to take responsibility for your own safety. I don't own or carry at the moment, but recent events in my life have led me toward the position that it might be a good idea to start.
To the OP: does the slide ride inside the frame on your CZ? It looks like it might from the photo. I'm not sure if I like the look, but it's definitely unique, and as long as it shoots well and you're happy with it, it's all good, right?
