Then saying not at all, isn't exactly true.
You can use secondary fire! After all the weapon only has one mode of fire, all it means is players have to learn that secondary fires the weapon.
End of the day if you sit around waiting for mod features to be implemented into public releases of mods to solve scripting problems, your're just wasting your time. In my opinion when I come across a limitation I try to get around it as best as I can, if a feature gets added later on that solves the problem then thats fine, but I'm not for sitting around and relying/waiting on the devs, its silly (lol nothing personal to oc devs or anyone, I'm just saying). I've seen people held up waiting for features to be added, and then their projects die of waiting.
I'm just saying I try to do the best I can with what I have available to me. In my opinion a weapon that uses secondary fire is no big deal especially if the alternative option means having no weapon at all.
