Replacement Hammer for USP 9MM SD

I talked to Jeff at H&K Customer Service on Monday morning ( about 10 actually ) . I explained that the polymer on the hammer was delaminating from the steel part . Jeff asked if I would like to return the frame for installation . I told Jeff that I had time I would do it , no problem . Jeff said he'd get one out . He did !!The hammer arrived yesterday ( Wednesday ) ! I installed it last night , I'm good to go today !! This was a warranty issue so their was no financial transaction .The hammer is smooth .......
I would like to thank Jeff and the crew down in Columbus !! Great job ! Great products ... Great people ! Have a good day ......
Thx,
Mark
