I was shooting a friend's G23 last weekend and experienced several light strikes. The ammo was Sellier & Bellot full metal jacket. Out of 50 rounds I got 4 light strikes. On each of those 4 cartridges, I observed a faint striker indent on the primer. When I loaded those rounds back in the gun and attempt to fire them again, all would fire on the second strike.
Does anybody know if that's a primer issue with the S&B rounds or does the G23 have a dislike for certain "hard" primers?
BTW, the gun was a second generation pistol, very lightly used, probably had only 200 rounds through it.
