We know many of you are excited to use your M12 Sidewinder with these new EPM1 magazines. We certainly can't imagine loading 250rnds with a thumb loader. Due to the EPM1's seriously high capacity we recommend making sure your M12 Sidewinder clutch is properly adjusted to handle filling your magazines completely. Do not simply tighten your clutch, proper clutch adjustment instructions can be found on our "Troubleshooting" page.
