I had no trouble with mine in my 1917 Artillery Luger I loaded
32rd and shot all 32rd with out a jam.After the last round the
hold open did not hold the bolt open because the cut out on
the drum tube is a tad to high,but no big deal as I was not in combat and did not have another loaded and readey to go.
I love my repo drum for what it cost me along with the repo
loader.
Thanks,George Fortier
