While writing my story recently I encountered a hitch when describing firearms, because the character has an extensive knowledge of firearms but when I write I find myself just putting down the name of the gun, instead of describing it as I don't know how to describe firearms! My other issue is that I don't know how to describe a gunfight from this characters perspective as I have never fired a firearm before and he is supposed to be highly trained. I've included an example if my issue below. "I fell down on one knee, drawing my Llama M-82, I rolled aside as his leg swept out in an effort to catch me, I fired two shots upwards into his groin and abdomen, his Protecta clattering the down as my third shot took him in the head. I leaped to my feet and immediately dove for the car as his companion filled the air with pellets behind me"
