I bought a semi us made trigger pack from hkparts. Don't have the parts to build it yet and was just playing with the trigger pack and have a question. When I pull the hammer back it rarely locks the hammer back. And only if I jiggle the bar on the top left side. Is that normal or should I get a hold of the vendor

Is it in a proper housing?

Does it have the selector lever installed?

the bar on the left side is the ejector an has nothing to do with hammer/trigger/sear.

If the hammer does not lock back every time, there is something wrong. I suspect the sear spring or trigger spring is installed incorrectly. It is a rather simple mechanism. Rotate the selector so it points at 12 o'clock, and push it out. Pull the whole trigger mechanism housing from the grip frame. Snap a pic of the underside of the TMH.

Unless this is one of the "Bill Springfield Trigger Job" units, in which case, you are seeing hammer follow, and should return it. Bill Springfield is a dangerously incompetent hack.
