I guess I lean heavy the other way. I have shot all my carbines. After all they are combat weapons, designed to be shot not safe queens. If something were to break, I have spare parts.
I'm skeptical when someone says they have an "original". Who really knows if what we like to call our originals, and I think I have some, are the way they came out of the factory. I think most guns that sell as originals have had something done to them. Maybe a part changed in the field. Or after the war. It could be the same type and marking. Even later someone dressing it up to look original.
I think unless it was a presentation gun, with provenance, it has been shot. And probably more then we think.
But that's just my 2¢
