It is my impression that model changes with different barrel weights are also at issue here.

Ruger first introduced the Creedmore in a 1B model with the 26" medium or standard weight barrel. These disappeared pretty fast and are scarce on the ground now.

Then they went to the 1V heavy varmint barrel at 24" in length. (The heavier barrel would optimize its use in long range competitions as it would not heat up as fast? Not many would carry this one in the field for deer etc.)

Is there a factory issue 1A in a light or sporter weight barrel at 22" for use as a hunter?
