I copied this from the forum about Wilson Combat break-in.

To break in
1) Make sure your pistol is well lubed
2) Shoot a few hundred rounds (300-500) through it prior to a thorough cleaning. (The slurry of the oil and unburnt powder burnishes the Armor-Tuffed mating surfaces and will give your pistol a glassy smoothness that our guns are noted for.)
3) if you have a malfunction, note which magazine and keep track.
4) Clean at 300-500 rounds If all goes as planned, lightly lubricate and enjoy your new pistol.
What they are saying there is that you are going to do what is called fire lapping for us instead of us hand lapping the fit, you are going to fire lap it.
