I had a batch of 124 from freedom that had same problem with primer just used them for practice ,I have shoot a lot of the 147 with no problems I did call them they offered to take back and replace,keep them anyway and still buy from them
I think this makes all the comments about stripping the gun to do some detail cleaning logical. What makes a trigger feel mushy, far less crisp, and lighter? Buildup that slows down the movement of the firing pin? A broken or damaged spring? In my mind I can't quite understand a hard primer making the trigger act this way.
