They certainly got respect in the Great War. Fine rifles.
Carcano is a lightweight, fast-handling, accurate rifle firing a true mid-power cartridge and having light recoil.
The rifles are just about bomb-proof, the design and materials are MUCH better than they are given credit for being. Truth is, the Italians put their money into STEEL rather than into making it look pretty.
The entire series (except for the Model 41) has gain-twist rifling, so the barrels should never be chopped.
Barrels last halfway to forever and many of them are honest 1-MOA rifles.
They are also the cheapest classic Milsurp available, apart from the recent influx of Russian '91s.
What's not to like?
Personally, I have seven of them and like them all.
