To be concise with your question I need to know if I had just purchased the firearm, built it from scratch, or modified it before I can answer my actions for ‘break in?’
@lonewolf well since it has been a half hour I am going to assume you are having problems looking it up on the Internet so let me help you.
Pretty easy break in process for pistols…pretty much the same whenever you shoot a gun actually.
Personally, I will run 100 rounds after modifications to get the ‘feel’ for the pistol again. I field strip and visually inspect parts, clean, function check and reassemble. My Glock was the only ‘trigger kit’ installation that I had performed as far as pistols are concerned. I regularly field strip the Glock at 1000 rounds because of the ‘abuse’ that it is known to accept ( I usually just ‘eyeball’ the carbon tracking on slide removal.) My Ruger SR22 is my carry and target pistol so it has only been field stripped. Because of its frequent use, it is cleaned and function tested, reassembled every 500 rounds. There was no modifications made. However, I have 3 barrels that I interchange when I target practice depending upon distance. And no John, was not looked up. I am not typing well this morning.

ADDED ANOTHER 30 mins. later… This is what you are asking of me???
