Mas, I tried to post this in the technical forum, before I realized that it was inactive. I have been shooting pistols for many, many years, but I did something today for the first time. I accidentally shot a 9mm jhp through my new gen 3 G23. It made a squib sound, but cleared the barrel, though it did not cycle the action. The case was bulged, but I saw no visible damage to the barrel or other components. I fired a 15 round mag of 40 through the gun immediately afterwards, and it was perfect. Other than being more careful, should I be concerned about my pistol? Many thanks.
