It's a one man operation so I'd allow at least a month. On a positive note, I have two of them for my Ruger SBH Bisley Hunters and really like them. They are a cheap way to tighten up the cyl play and also the Keith that I have is much easier to grasp than the standard one.

I think it's debatable if this is a positive thing in a non-line bored gun, however. I have noticed no detrimental effects with my guns, however I don't run them hard or in high volume. It makes sense how the removal of cyl play on a gun that has imperfect barrel cyl alignment may hasten forcing cone erosion though.

I am not a gunsmith, so maybe someone more qualified can opine.
