One of the many advantages of the simple, break-open action of the H&R/NEF rifles/shotguns is the reduction in overall length compared to any action (bolt, lever, pump or semi-auto) that needs to leave space for a reciprocating bolt.
So with that going for them, you would think that H&R would make some rifles with 16" barrels and shotguns with 18" barrels (or 16 1/2" and 18 1/2" if you prefer) to really showcase this. For deer rifles, camp or range guns, survival guns, you name it, I would think that the significant length (and weight) advantage would be a big selling point. Yet H&R offers none of their rifles in shorter than a 20" barrel, ditto the shotguns, and most longer.
For example, I personally would love to see straight-stocked carbine like the CR-45LC but with a slim, 16" barrel in .357 Magnum/.38 Special. It would be a great gun for cheap plinking in .38, could take shotshells for snakes or rats, and would even make a good deer gun in the woods with a hot .357 load. I could also see a breakdown rifle or shotgun, maybe with the barrel packed in a hollow stock like the old AR-7 survival rifle (still made by Henry Repeating Arms Co.) or all the pieces in a nylon back like my Marlin Papoose.
So why are there no short-barreled H&Rs?
