This is lifted from another post: "see if a yellow pencil will drop into the barrel erasure first. If it will it's a 9MM."

Go get a yellow pencil and stick it into the barrel, and tell us what happens. Or if you have a good set of drill bits, carefully see which on will fit and also the first size that will not fit. And give us those sizes.
