I have two RWS 34's in both common calibers. My .22cal rifle has a problem with the barrel pivot bolt coming loose. My .177cal has no problem with this issue but it appears that someone put some kind of Loctite material on the threads of the nut. Any of you guys have this issue with any of your breakbarrel springers? Would Loctite 242 (blue) be the answer for this problem like it is for stock fasteners?
