In time you'll get over being so anal about your brass, there's too much good stuff on HBO to worry about sorting pistol brass.
Brass splits, some sooner than others but if you want to set your mind at ease that it may be something more serious take a dry Q-Tip and slowly run it up and down the chamber of your barrel.
If it snags anywhere yse a bore light and magnafying glass to check for the rough spot and possible pitted area. A very rough spot or pit will cause the case to split during extraction. The area can be buffed out with no problem so it's nothing to get worked up about.
Chances are you simply have a batch of weak brass but if it continues to happen with all brass find the problem through prosess of elimination.
