Thanks Nick. The spring problem seems to be common on Walther and HW rifles but, at least with the Walther, it's very easy to sort although I agree we shouldn't have to.
Overall I think the quality of the Walthers is higher than the HWs but I can only speak about the ones I have experienced. There's absolutely none of the twang that used to drive me mad with the HW's and everything seems very solidly engineered. A nice CS stock (if they do them) would be the icing on the cake I reckon.
