I prefer full moonclips, to speedloaders, to rapidly replenish my S&W 627s. If possible, I would like to apply this same approach for my Ruger GP-100s. Is there a moonclip for the GP-100 that will not harm the revolver?
You would have to have the cylinder modified. The 627 guns come from the performance center with the cylinder cut for moon clips. Various smiths will modify other (six shot) .357 guns for use with the clips. I have only seen this done on *&* guns, but don't know any reason it couldn't be done for the Ruger. Assuming that someone has a source of clips with the right spacing available - I don't know how a GP100 and a 686 (for example) compare on chamber spacing. I suggest the following website for more detailed information:
