Hi Eugene! It is pretty much a necessary operation to hit the toggle with your hand to close it on the first round... Just pulling it back and releasing it will not do the deed???
.... If you think about it... even normal mags loaded with 8 rounds sometimes need a tap to close.... Let me know as you become more familiar with the drums operation... they will all have their own kinks and it's going to take some effort to get them running 100%... In the next few weeks, I will try to post a trouble shooting flow chart.... God knows I've seen just about every problem they can have???.
... Best to you, til...lat'r.....GT....
