Marv's RISE Armament RA-140 was apparently not up to the rigors of the increased bolt velocity from adding a can to it.
The nice sharp edge on the back of the hammer is a well radiused edge and the disconnector doesn't want to grab it anymore.
Getting fairly consistent hammer follows.
That's unfortunate to hear. I've got 3 of those RA-140 triggers, although I wasn't planning to use them with a supressor. I'll have to keep that in mind if I ever do.
