I have my custom user title set for my favorite line of pistols - the Springfield Armory XD Series. I did that for the sake of clarification for the reason you mention above. I also do my best to state as much basic information as I can about my firearms when I post - for the very reasons you mention above. Same w/terminology. I've always found it somewhat rude to assume that everyone knows what an acronym is, particular "thing" might be or just what you're on about if you post a somewhat cryptic question/line that requires the reader to be on the exact same mental page as you.
Just sayin'....
BTW, when I saw the thread title, I thought you meant "giving your gun a name". My two XD-40's have names: Dean and Sam Winchester. The name came about when I first brought the SubCompact home w/some Winchester PDX rounds. I thought it might be fun to get the family involved by asking them if they wanted to give the pistol a special name. Wife said "How about Dean or Sam Winchester? Name it after the box of ammunition." The kids loved the idea - my daughter, Wife and I are all fans of the TV Show "Supernatural", which features the brothers Dean (the older, but shorter brother) and Sam Winchester, who hunt monsters, ghosts and demons.
So, the Sub-Compact became known as Dean, which is fitting as Dean is the older, somewhat shorter more compact brother. Three weeks later I purchased the XD-40 Service (4" barrel) and it was immediately christened Sam, who is the younger, taller brother. Silly little story, I know. Maybe I'll start a separate thread....
