Okay, I wasn't sure if you would have a thesis-based Masters or if it would just be a course-based Masters. Have you thought about not doing a full Masters (and just take some graduate courses in your interest field instead) and just doing a Physics BS, and taking minimal courses (since it sounds like you will be able to finish a 4 year degree in less than 4 years) in order to do more research? I'm not sure what kind of program you are in though, if this will work.
At my current US school, although it's possible for undergrads to tack on a Masters with their BS if they take a ton of courses at once, I really think it's more beneficial to just take the relevant courses and spend the rest of the time working on research. I don't think having a Masters will help you get into grad schools at all and once you are in a PhD program, you're going to get a Masters through that program anyways. I am also not sure a MS thesis added to your 4th year of undergrad will be much different than a senior thesis anyways. Unless of course, your program doesn't allow you to easily do thesis level research as an undergrad and the only way to get this extra research experience is to do a Masters.
The bottom line is, in my opinion, I don't think having an extra piece of paper or line on your transcript from the MS will be very helpful. If there are a lot of extra courses required for the MS, I think that time would be better spent on a research project (but still take a couple of graduate courses that interest you). However, if you will not be able to get the research experience without the MS, then you should do the MS option as a means to get more research experience. Don't do the MS just to get more courses under your belt, or just for the sake of having a MS, because since your goal is grad school, you'll get all this later anyways.
