For 2008, Sturm, Ruger & Co. introduced the model KRH-45-4 Redhawk Revolver chambered in .45 Colt.
In 1979, the Redhawk was introduced in a variety of chamberings, including .45 Long Colt. However, over the years Ruger scaled back production so only the .44 Magnum was available. However, with the renewed interest in revolvers, Ruger has reintroduced a .45 Colt Redhawk.
The .45 Redhawk is available with a 4″, 5 1/2″, and 7 1/2″ barrels. The double action Redhawk features a triple locking design for strength.
Ruger states the KRH-45-4 has a “rugged frame, designed specifically to handle powerful magnum loads, (and) includes extra metal in top strap, sidewalls and barrel mounting areas.” So, this Ruger should be able to handle the hot handloaded hunting loads and the commercially available hot loadings offered by companies such as CorBon.
Ruger is taking orders for these revolvers now.
