I just purchased my first handgun, a Smith & Wesson M&P9. I will pick it up on Saturday. I was just curious if there is a routine or procedure that is recommended to break in a new pistol? I know the M&P falls into the same arena as Glocks, which many suggest no maintenance is required. But being a mechanical guy, it goes against my better judgement to treat any mechanical device in such a manner. I look forward to your feedback.
