If there were any interest, I could try to do a video or pictorial on how to unload the various types of weapons you may encounter. I have never done anything like that, but I do have one of every "type" of pistol. I am sure this wheel has been invented already though.
I just googled "how to unload a pistol" and found a video for pretty much any type anyone could want. I think I'll have a quiet word with my training officer at the one service where nobody knows about guns. I doubt he'll go for it, but it can't really hurt to suggest.
