J.C. Higgins .22 with a Sears(Weaver) J-4 scope. Yes, I still have it. Got it the same year my wife was born. These guns were made for Sears by Marlin.
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.
My first firearm was a Mossberg 600AT, 12 guage shotgun. Sold it to a friend from work who was just getting into dive hunting. Used the money towards another shotgun (Rem. 11-87).
Remington 870 16 Gauge shotgun. It belonged to my uncle when he was a kid, and unfortunatly being the jerk he is, took it back in my 20s. (he has never used it since)
My first gun was a Taurus .357 magnum revolver. Still have and probably always will. Cant beat the reliability of a revolver! My second gun was a Beretta PX4 Storm in .40 cal but I soon traded it for the love of my life, a GLOCK 30 .45 cal. Hope my wife doesnt read this!
AYA side-by-side double barrel shotgun in 16 gauge. I still have it. My Dad got it for me in 1963 from the same place Lee Harvey Oswald bought his Carcano carbine; Klein's Sporting Goods in Chicago. I still have the invoice.
My first firearm was a Christmas gift when I was 17, it was a Remington .22 auto model 550-1 and would shoot short, long and long rifle reliably. It will also chamber and cycle CB longs. After 40 years it now sits in my safe and sometimes still fires a few rounds from time to time. This rifle has stayed with me when almost everything I bought myself over the next 20 years has come and gone. Now anything I get I generally keep.
