Here is what I have run into in the last two times I have used Lone Wolf UPK.

You can see the difference between these safety plungers.
It may not make that big a problem with a gen3 trigger bar because it runs across the plunger at a different spot then a gen5 trigger bar. The gen5 trigger bar seems to be the one that I have trouble with.
So, I have a question.
Am I missing something here, are there a tall and short safety plunger one for gen3 and another for gen5 trigger bars?

Indicated by scoring in the area just below the safety plunger? Yes, you can see some drag marks on some plungers that are setting high. My PF45 build was the first time I had problems with safety plungers. For me the only time I have had this problem is with a gen5 trigger bar. The trigger bars that have the dot on them to let them ride on the center of the safety plunger where as a gen3 trigger bar rides on the side of the safety plunger. There might be a deferent angle on the shark fin in the trigger bar too, but I have not checked for that. If you have a LW safety plunger with a gen5 trigger bar in your PF45, this could be a drag problem for you.
