Like the title asks....what was your first firearm?
Remington 870 express for me. Circa 1990 at the age of 13. It was a Christmas present from my Mother. It took lots and lots of begging, whining and rationalizing but she gave in and put it on layaway at Kmart. My justification for needing one was that my best friend who lived on a huge farm had gotten one when he was twelve...and he hadn't shot his eye out yet! Times were good. 22lr was $7.25 brick and a box of low brass birdshot could be had for under $4.
It is now my ugliest but most cherished firearm.
