Some I have just shot, others I have spent long hours breaking in. While I was in Germany years ago, a Tech-Rep from Sako visited the Rod and Gun Club on base, he recommended (on their rifles) clean the gun throughly, set up on a bench, fire a shot then clean the barrel with a brush and patched until clean, do this ten times, then fire two shots and clean, do this five times, then fire five shots and clean. He said the barrel should be broke in at that point and capable of delivering tight groups.
I tried it on a couple of long guns, I don't know if this is the reason but they do perform well. I never tried this on a pistol, but don't see why it wouldn't help in breaking her in.
