Posing this question based on recent malfunctions I’ve had with my PTR-44, where the hammer spring tails first slipped off the notches on the disconnector after about 10 rounds, preventing the sear from releasing the hammer. After reseating them, I was able to fire a few more rounds before another failure to fire (slack trigger). Dropped the trigger group and discovered that both tails had again dislodged, and the flat rear end of the disconnector had been completely sheared off. My first instinct was to check for any wobble of the hammer along the axle, which would have caused the hammer to be driven back at an angle and dislodge the spring ends from the disconnector notches. Hammer seemed to rotate straight back between the hammer spring ends with no slop, also sear had no wiggle along the axle. Completely at a loss as to why the disconnector was broken in half, other than being improperly heat treated.
The Sturmgewehr’s trigger group is a Rube Goldberg mess, but I can’t imagine this happening often in the field during WWII. Anyone else experienced this problem in a semi build or SSD repro? Seems to be a weak point in the design if proper trigger function depends on the hammer spring staying seated in the shallow disconnector notches.
