Well, I just don't consider a gun part of the family until it's been properly named.
Here are a few.
Dad has always lovingly called his .270 "The Meatstick". It's been keeping the freezer full for 20+ years.
My .270 is called Buster. Kinda old and heavy, but dead-on reliable.
My 7mm Mag is called Maggie, after mule that kicked the snot out my brother when we were kids.
An OLD, but very nice L.C. Smith SxS 20 Guage goes by "Elsie"
I have two Winchester 12 guage pump shotguns. one with an 18" barrel (riot-gun) and another with a 28" barrel. They are Laverne and Shirley.
My heavy barreled 22-250 is called Nickie. I put 5 shots under a nickel at 100yds.
And My P220 is called "Skunk F***er". I got "charged" by a skunk shortly after getting her, and pulled off a sweet double tap before the skunk could get a shot off
. First shot hit the body, second in the head.
