After shooting 200 rds I wanted to field strip and clean my new pistol. No problem taking apart but when I removed the bolt a small piece (metal chip) fell out also. After insepcting the bolt it looks like a small chip had come off the recoil spring assembly at the end of the spring guide. I have photos that should help explain. I reassembled the pistol and it seems to function properly but I have not shot it any more. Is this a major problem? Can that spring and/or guide be replaced by me? and if so where is the best place for parts or repair if I can not do it.
