How many gun-using roles does an actor need for inclusion on the wiki?

[Mazryonh]

I noticed Ingrid Bergman's page recently. She only has one gun-using role included on this wiki, and I do remember more pages like that (though the names escape me at the moment). At least a case can be made for Ingrid Bergman can be made that she was "significant" enough to cinema history. Just how many gun-using roles does an actor require for a new page for him/her on this wiki anyway?
