This sounds to me like the sort of versatile weapon that might be worth buying and storing away for any long term emergency, rather than carrying around in most situations.
The was a little tongue in cheek. AFAIK they built around 500 of those revolvers. The extractor was more fragile than that of regular double action revolver and definitely more fragile than the ejector rod of the SAA type.
Possession of a gun that accepts a wide range of ammunition could be literally a life saver.
I think thatīs only true if you can actually hit something at some distance with it. That tends to be a problem with guns that accept a wide range of ammo. Twist rate is a factor here.
Worth considering IMHO as a long term doom prep, rather than for routine hunting or defensive purposes. You might never need it, but that is true of many doom preps.
For long term doom prep Iīd rather have a bow. The ammo can be improvised, practice keeps you fit and it may outrange a revolver that is used with the wrong type of ammo. Itīs report is much quieter too.
