+1 on what muskrat said. I have a stoeger stf 3000 20 gauge which is just an engraved condor. If you dry fire it it'll only fire one barrel. After you dry fire the first barrel, if you bump the recoil pad pretty swiftly against the floor or something else solid it will allow you to dry fire the second barrel. The only trouble that I had with mine was when I let a friend's kid shoot it. The kid didn't have it held tight enough to allow the recoil to let it fire the second barrel.
