We talking firearms or guns in general. Hand me down BB & pellet rifles were the first guns. Winchester model 37 single shot 12 gauge w/ full choke was my first firearm. Traded it off for my Ithaca model 37 12 gauge. Once I got married I found one & bought it for the wife for her birthday.
Bought my first about 10 years ago when I turned 21. It's a HK USP compact 9mm. Still have it today and actually put 250 rounds through it yesterday for a total of about 50K rounds. Never had a single malfunction with a and it still remains one of my favorites. Here she is with all her purdy wear marks.
