Moonclips?

[Retired LTC USAR]

Have both a 610 and a 625 which both use moon clips. The moonclips
for my 610 have a round center while the moonclips for the 625 have a pentagon shaped center.

Are the shapes particular to the manufacture or the weapon they will be used in?

Different makers have different shapes. As long as the moonclips fit over the extractor star you're good to go.
