I say you should press on, the situation seems somewhat analagous to suppressors here in the states. As the relative cost of suppressor ownership has dropped, suppressors have become more and more popular. In the last couple years it seems as though suppressor owners have finally reached the critical mass necessary for some small legislative changes to start to be implemented. Specifically, several states have passed laws allowing the use of suppressors while hunting. It's not huge, but it's a start, and with the potential inclusion of hunters, the numbers of stakeholders in the suppressor conversation has grown.
While this is only tangentally related to your topic, what I'm trying to say is you can never reach the critical mass necessary to start getting things done if people allow the government to make the choice for them. If you ever want the situation to improve in your country, you should re-up your handgun license, and focus on introducing the uninitiated to your side of the gun rights discussion.
