for durability,buy the Ruger
all the Italian made colt 'clones' are inferior to Rugers' where it couints..on the inside.I say this as the owner of 4 clones,and 1 35 year old Blackhawk that was used hard for wax-bullet competition.
the clones have been worked on many times over the years,the Ruger just keeps going.
why do I have the 4 vs the 1 ? I love the heft and feel of the clones,the ruger is a sledgehammer,the clones are a finishing hammer.
imho,ymmv,all that jazz
