Nitros are pretty solid, for sure. So are Western Long Range, and there was some question about their strength because the receiver is made from malleable iron. Does not seem to have resulted in many failures. Those were the days when you could get good, American-made guns at the local hardware store. Nothing fancy, but a reliable tool.
Being worried about the receiver on a Western Arms gun is like being worried about the moon falling out of it's orbit and crashing into the earth. I'd bet there were NO failures of frames on those guns. I used to own a 12 gauge Western Arms, would have kept it, except some depression era soul opted for the single trigger, and I couldn't wrap my head around using it.
I shot a few grouse with the gun.
I wonder what a gun like the Nitro Special would cost today, if some company decided to produce it? $2500?
Doesn't matter, nobody will.
Bobby, your experience seems to be about par. Just solid users that don't cost a fortune.
Best,
Ted
