Nostalgia is worth couple farts. I would buy .44 Magnum instead. That way you can shoot .44 Magnum and .44 Special through same cylinder. Ruger offers SA with handi 3,75" barrel in that caliber.
The advantage of the .45 Colt/.45 ACP option is the much more available and less expensive .45 ACP ammo. That cannot be said of .44 Special.
