357 Sig magazines for DI uppers

[HMC710]

The 357 Sig continues to be in the top 2 of our builds and we are working on getting better magazine options other than running glock mags in a glock lower. While the glock mags/lowers work, the geometry uses up a lot more bolt energy and is not as smooth as we would like. THe CMMG pmag coversions are only good for loading a few rounds if that, but the flat profile of the case runs smoother.

We printed up a mag yesterday and are working on some mods for it. We also mocked up a colt style mag lower and ran rounds through that yesterday and will look at an adapter to see if that works.

Merry Christmas!

Got the Sig Colt mag adapter done yesterday and ran a few rounds through it. Need to get some more reloading done and tweak things a bit, but it was successful. Will updated the dedicated mag when I get a chance.....

Our new Sig AR mags! Hot off the press.


Sig M2 mag for testing. You can see the Colt mag adapter next to it.


Swapped material for the Sig M3 and will run a batch for field beta testing.

Got the new material in and tweaked the feed ramps a bit. Working good, but limited on capacity so working on that.
