I really thought it was much more restrictive.
In the situation you describe, would you need to be doing something related to the club (coming or going, club business, etc) for the law to look favourably on your use of the weapon? I mean that if you just went somewhere with a gun, some public place, and you ended up having to use it, how would that be viewed by the law?
If police wanted to make a fuss about it, they could probably make things uncomfortable for you in such a case, but in practice, I've never heard of that happening, and it would bring up a lot of other issues.

Provided your use was justified (that is, that the threat was real), there wouldn't be a problem. If your use wasn't justified, I suspect they might try and use it against you, but you'd have much greater legal problems.
Where it would get you in trouble is if somebody went to a bar looking for somebody they were having an argument with and then shot them - they might be asked some very difficult questions about whether they were carrying the weapon with the deliberate intent of using it, rather than just happened to be carrying it when a situation developed they were not anticipating. But exactly the same situation could apply if you walked in carrying a golf club without any obvious reason it was on your person. In such a case, it could wind up a matter for a jury to decide whether the circumstances were reasonable or not.
