No real complaints about this gun but there is that recurring loosening of the recoil plug. The one that you unscrew before releasing the guide. I note that Springfield sells a guide and plug. Is this meant to remedy this problem? They won't answer my email. Also, I can't get the bushing loose with my plastic wrench from Brownells and am unsure about whivch way to turn it. I have been cleaning the weapon leaving it on but that is getting to be a nuisance. Any help appreciated.
