My general rule of thumb about break ins (guns, cars, whatever) is to follow the manufacturer's instructions. I'm inclined to give them a little credibility when it comes to their own products. If a manufacturer doesn't say anything about a break-in, then my assumption is that the gun should function without issues from the first round. Beretta, for example, has a machine that cycles at least some of their semi-auto pistols numerous times before they leave the factory. That probably has something to do with why they don't talk about a break-in period on their products. Other gun companies (Kahr is one) mention a break-in period and provide a round count. After that round count, the assumption is that the gun should function without issues. It's not a given that it will malfunction before that round count is reached, but if it does, it's not a big deal. That said, even during the break-in period, I wouldn't expect to encounter a lot of malfunctions. The break-in isn't supposed to work magic, just allow the rough spots to smooth out a little. I really don't care one way or the other. One way you pay a little more for the gun company to smooth things out for you, either by machine-cycling the action like Beretta does or in extra finishing operations. The other way you pay a little more for ammo and time to shoot the gun and smooth things out yourself.
