I have a small covey of double-single trigger Brownings and never had a problem with any of them. They do not have a reputation for problems. Inertia trigger Brownings are a royal pain. If they weren't such great guns, I would sell all the inertia trigger examples.
I owned two Twin-Single trigger guns for a while. They're really great, and the one gun is the only shotgun I've ever sold that I regret selling.
...as of tomorrow, I'll have five Superposeds:
- 1959 12 gauge Browning Lightning. 28" barrels, inertia trigger.
- 1970 Fabrique Nationale B25 A1 "Special Skeet." 28" barrels, inertia trigger. This is a really cool gun.
- 1971 20 gauge Browning Lightning. 26" barrels, inertia trigger. At 6 lbs...this is a grouse gun...
- 1974 Fabrique Nationale B25 A2. 30" barrels, mechanical trigger. This gun is almost unfired and has a very nice looking, and original, case colored action. Just a hair over 7 lbs., it's a keeper.
- 1977 Fabrique Nationale B25 B1. The gun in the pictures above. 30" barrels, mechanical trigger. It will be here tomorrow, so that's all I know at this point.
