Mas: You seem to be knowledgable about the Glock firearms. I just bought a Glock 30sf. When I field stripped the gun the recoil spring guide seems to be weak on the end that contacts the bottom of the barrel. I compared it to my Glock 36 recoil spring guide and the part in the G30 doesn't appear to be as strong as the part in the 36. Do you kow if there have been any problems with this spring guide? Thanks for any knowledge.
