I don't have a set break in period, but for the most part I run 50 rounds through a clean gun. Clean, then run 200 rounds through. This is usually cheap FMJ ammo. Clean, then I run 50 rounds or so of whatever HP I will carry.
I use 3 or 4 magazines that I will plan to carry as well. Any FTF and that magazine goes. I always load a full magazine, rack the slide from the slide stop, and then top off the magazine again before firing, since that is how it will be when carried.
If no FTF at that point, I don't worry about it. It still gets shot quite a bit after that anyway.
Most of this shooting is at an 8 or 12 inch gong at 25 yards. If I can't hit the 8 inch gong most of the time and the 12 inch gong all of the time, I'm worried. It won't be carried until it can.
