I respectfully disagree. A dry lube will help slick up polymer on metal. The advantage of a dry lube is that it does not attract and hold dirt or firing residues as oil or grease will.I use Hoppes #9 solvent for cleaning. Being I live in a sub-tropical environment where thickening of lubricant in not an issue, I use Lubriplate to lubricate the pistol. You can clean the striker channel with solvent but ensure it is completely dry. Nothing should be used to lubricate the striker channel, not even dry lube. There is no metal on metal contact in the striker channel, there is only polymer on metal contact. Using dry lube has absolutely no benefit.
