OO:
I installed some on a Pard's pistols awhile back. He said they were Bullseyes, but no mention of Qualite.
He got 'em a gunshow. No label!!
They went on with NO gunsmithin'. That's good, I'm not a real gunsmith, although I play one at some SASS matches.
I reckon the rods on them new "li'l" Vaqueros would fit & you'd have factory parts.
I have a set of Qualite gripframes comin' soon. We'll report back on how them fit.
