Are you sure you wouldn't like to revise and extend your remarks? :-)
Given that I do not consider myself an expert in firearms (though I am a fairly regular user of same, being a target sports enthusiast); and given that my "remarks" published above are the residue of knowledge made available to me only through the kindness of friends, whom I believe are deeply expert in their field, my answer to your question is: NO. Though I'm sure if you were to pose a succinct question, I could refer it to V, S, or D and get you a decent answer....
That is to say, if you would like to ask a more specific question, I'd be more than glad to research the issue -- which in all probability would mean I'd readily consult with those friends of mine whom I consider (with reason, I believe) to be the real experts on issues like this.
I'm waiting.... Do you have a question for me (them)?
