I shot the P-09 last week at 100 yards and the gun was fine until the last 20 rounds or so out of 60. The last 10 rounds were scattered. I went home, borescoped the barrel, saw some uneven carbon levels in the grooves. Gun had about 300 rounds without cleaning, but the barrel has some very shallow pitting so I wasn't sure what effect cleaning might have. So I gave the barrel a medium cleaning effort this morning (no abrasive pellets, just brush, solvent, patches) and took it back to the range to shoot 40-50 rounds.
https://youtu.be/CkkYR6iqtOgGun is fine once again! I've never shot 4 10 ring hits in a row before, and, for the day, I had 3 five sequential shot groups of around 4 inches. But my eyes were getting fatigued after 30 good rounds so I went home at 50. Lesson learned, this old barrel needs a little attention more often than some of the lower round count striker pistols I have.
I'm about ready to go back to the P-10S for a few range visits next.
