OK, what is the Moon Clip trick????

...or just get the Rimz and don't buy all the 44-90 dollar tools. YMMV.

Those are probably fine for range toys. Doubt you could do this with Rimz tho:

I bought a couple of these from Amazon. Simple and Cheap at $7.62. https://www.amazon.com/gp/product/B000U3UQYW/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 They work just fine and no futtsing around building my own.

If you're a skinflint this is the right answer. S&W 625s typically include one. I've got a couple. Otherwise get the moon clip tool or BMT.

They don't. But scissors do.

Just snip the Rimz in half.

I thought of that. But that only gives me 4 rounds. (You have to slice up 2 of the 6 slots.)
