Good choice, as I have a Ruger Convertible as well. Nice to be able to shoot the .45 Colt & the .45 ACP.
The .44 Spl IMHO is better for most shooters than a .44 Magnum...one seldom needs the power of the magnum for target shooting and plinking. Also, the .44 Special is an inherently accurate caliber to shoot. As I have mentioned, very nice with a WC style bullet. Also it shoots superbly well in a model 29 and a Ruger Suberblackhawk..in fact better than in a model 24.
