Here's a very interesting gun made by Takara Tomy. A few interesting notes:
1) You need to assemble it.2) It can really shot out "tiny plastic bullet". [Yes, it can shot out tiny bullets!!!]
Please noted that it is NOT exactly 1/3. It is around 1/4-1/5. If you are very sensitive to 1/3 ratio, we do not recommend you to get it. But it is definitely a very fun props for our girls.
