I always clean my Smith M&P 9 after every shooting session, but I realized the other day that once I field strip, I always just set aside the captured spring/guide rod. Is it a good idea to scrub that puppy with a toothbrush and solvent as well? The gun makes kind of a creaky/squeaky sound when I work the slide. It sounds like the spring grating against the guide rod. Could this be from a dirty guide rod? Or is it normal?
Thanks for the help.
