Hello, this is my first post. I was wondering if anybody else has or had this issue with their M37. My Grandfather bought me this new in 1976 for my 16th birthday bless his heart, and I have ran many of shells thru it since. The problem I am having now it is really hard to rack the pump with the barrel on and nut tightened, if I loosen the barrel nut it gets easier, or take the barrel off it's as smooth as new? I visually see no thread issues with either the bbl or receiver. And yes throughout the years their has been an occasional 3" reload ran thru it (shooting skeet with a friends huge box of assorted reloads). Perhaps the bbl got warped or over heated thru the years? something bent?
Thanks for any advice, I just thought I would ask some of you guys before I take it to a gunsmith so he can charge me $50.00 to tell me I need a $300.00 bbl. Roger from Lapeer, Mi.
