I have both guns...the #57 HKS Speed Loader fits both..
Thanks they have H.K.S 57,with patent number. Now the question to myself, get a revolver they fit or get rid of them.
That's a foolish question. There are much worse reasons for getting a new gun
By the way, the .44 mag speedloaders I have fit my N frame Smiths and my Ruger Redhawk.
