Buy a 45 Colt Redhawk in your preferred barrel length and the cheapest 454 Super Redhawk you can locate. Disassemble both and swap the cylinders and viola! You have yourself a 454 Redhawk.
Yes I’ve done it and yes it works. If a guy is lacking scruples the Super can be sent back to Ruger for a replacement cylinder, I never did but know someone who did.
