Mikey or some of our other experts will give you a better answer, but I think they're the same mic. The labeling on the mic is identical; the model #s are only slightly different, as are Mitutoyo's global trade #s. The only difference I see is the '345' model weighs slightly more than the '341' - less than half an ounce, and depending on what they're weighing, that could be the case. More than likely, they're from two different production runs. The only concern I would have is if they are made in two different locations, one may be superior to the other. That's a guess. Mikey will know better.
