Soo.. issue: Fires on action release

The troubleshooting section of Gortz & Sturgess discusses rounds jamming nose-high, and attributes it to the mainspring being too strong. I can also imagine a too-weak spring causing the issue as Ithacaarist suggests. Either way mainspring seems to be a possible culprit.

In .30 Luger I have found on some pistols this type of jam can be caused by the pistol wanting a slightly longer-length round. So you might consider trying various ammo types to see if there is any difference. Winchester White Box 115 gr. is recommended baseline.
