In my case for the brass brand (standard bass without any kind of modifications) that I’m using, it didn’t work as fine as my other .040” moon clips. With the .037” they wobble a lot in my case, nothing to do with the quality of the product. Unfortunately, DAA didn’t pay attention on my order...

nice quality, I recommend
0.037'' fits well on my 929 with Geco brass
withanother brand on my previsous 986 7 shots, I used GFL brass, as Geco were too loose inside the clips and would sometimes not stay in place
with these DAA clips, GFL are a little bit too tight, that's why I now use Geco brass

strong and reliable, good !
.037" fits better for my 929, .040" make difficulties to turn the cylinder
with my previsous 986 7 shots, with another brand of mooclips, I had to use GFL brass, and Geco were too small and sometimes not stay in the clips. With these DAA clips, Geco are perfect fits...

For the money these can’t be beat. Nothing beats going to the range with 100 loaded moons. Maximize range time. Load and unload at home. They come easily off the DDA magnetic posts. I have occasionally lost a moon, maybe twice(?). I simply added a few more posts. 2 behind the left hip for initial...

Many serious revolver shooters use only one brand of brass and select a moon clip that works best for that brand. That may be the best practice but I am not one to spend a lot of time sorting cases. These DAA moon clips are very rigid and so far have worked well with a variety of head stamps,...

Best 929 moon clip available and at a great price too.

The Double Alpha 8-round 9mm Moon Clips are designed for the new and popular Smith & Wesson 929 9mm revolver.

These match-grade moon clips are comparable in quality and performance to the very best available, but at a more affordable price, achieved through volume and hi-tech production.

Our Moon Clips are laser cut from hardened 413 Stainless Steel achieving an unparalleled hardness of 44RC, making them extremely durable and resistant to bending and deforming. 

We now offer these popular moon clips in two thickness options: 0.037" (0.92mm) or 0.040" (1.00mm).

Depending on the type of brass you are using, and the headspace you have in your revolver, one type or the other will offer you the best performance. It's important, of course, to achieve just the right amount of retention of your ammo in your moonclips to enable the best, most consistent reloads. Choose the type to best suite your ammo specifications.

The stainless steel used is magnetic, and the smaller-than-most cutout for the extractor ensures more overlap and optimum performance when used on magnetic moon clip holders, such as our DAA 8-shot moon-clip holders.


Please note:

Brass dimensions vary greatly between brands and in some cases even within certain brands.

We have found that our moon clips work with most brands. However, for most brass, loading and unloading tools are required.
