I guess we will just disagree, I have seen it too many times, They stretch the spring and it definately looses tension, it also goes back to its original length in just a few hundred cycles. Kind of pointless. just replace it if it is bad. Now if your talking Flat springs it is a different story, a correctly manufactured and treated flat spring will hold (both tension and shape) when bent.
The point here is that if the spring has lost tension it is BAD, Stretching it just buys you a small bit of time.
But if the bolt carrier is draging then it is a completely different issue. I am surprised that you just did not send it back to mossberg. I have sent them old second hand 500's and they fixed them free of charge (i paid to ship them one way). and they are quick too. Unless thay have slacked on their CS lately.
Have you checked for burrs or signs of rubbing to try and locate the area that is causing the binding?
I would like to have one of these 935's but on here they seem to be about 50/50 or the good / bad ones.
