First SG I ever fired was the family Sears 12g pump. I'm not sure who even actually owns it, but it's been passed around for about 40years now. Thing is a monster. Has to weigh 20 pounds with a 30 inch barrel topped off with one of those big can switch chokes, the IC and Mod chokes disappered long before I shot it.
My first SG was a Mossberg bolt action 20g. My father was and is a huge fan of his .410 bolt but always thought the .410 was an experienced shooter's gun, not a beginner's. I still thank him for that.
Not long after that my Grandfather gave me my first true love, his old Stevens 311 12g. Many have come and gone since, but that 311 will be buried with me.
