I don't own many guns. They're expensive! And I wasn't lucky enough to inherit any from my family.
I've only got my nice 30-30 deer rifle (with a great scope!), a 410, a 20 guage, a 12 gauge, and a Ruger 357 mag.
Nothing really special about any of them, but my 30-30 has been my friend since about 2000, since I've shot 12 deer in a row with it every gun season.
The 410 is a shotgun I'm holding for my son (he used it in high school) and I almost never use a 12 gauge anymore. The 20 gauge is a cool pump that I use for grouse.
