I ran one dry patch through the barrel of the P-09. This is at about 200+ rounds, two local trips to the range and two trips in New Mexico. Rand the borescope down the bore. Lands were shiny, grooves had an even smooth carbon layer, chamber and leede area still nice. I didn't clean it. Put the barrel back in the slide, put the gun up. Will check it again after a few more trips.
