That's the question.
I'll be frank. It's hard not to look at this place and notice the sub-par quality of about 90% of the articles, especially the ones relating to weapon systems, protective equipment, and anything relating to rationale and thought in the selection of such things.
This isn't about me, so I'll spare any kind of in-depth explanation of background that - again, being frank - most people wouldn't believe anyway. Suffice it to say that there are nerds everywhere and I like to do consultation for authors in my free time, hence me being here after having it pointed out in a forum a while back.
If you've got a question about anything relating to firearms, their employment, selection of a firearm for carry, what makes one useful in a given situation, what makes one not, how they're carried, their accessories, etc, so on, and so forth, hit the thread up, and I'll do my absolute best to give you an answer that'll teach you something, and hopefully leave you edified in a way that lets you write more clearly and in a better informed manner. After all, it's much easier to write about something (even when it's fictional!) if you have a functional knowledge of the basic, more mundane things surrounding the topic you're writing about.
So open fire.
