I would guess the single barreled 12 gauge shotgun is probably the second most common gun in the US, besides a bolt action
.22. I have one made by Springfield / Savage. The M106 has a normal action release, not a tab or button like more modern cheap
guns. The stock fits me very well, and is smoot and graceful. I shot my first grouse and my first two deer with this shotgun.
Single shots encourage a young shooter to make more careful first shots, no spray and pray with a single shot. The single
shot is also usually much lighter than a pump gun or automatic. Because of their weight they are more likely to recoil harder,
especially for small people.
Despite the shortcomings of the single shot they are very good choices for many people. They are inexpensive, and point
better than most modern made plastic junk.
