I added the following background information as an "edit" to my starter post to answer a few questions:
EDIT: There were originally far more choices in the poll, including the Johnson rifles, Browning pocket autos, and others. However, THR limits the number of poll choices to 16, so I went with the more common stuff and put in an "other" category. For this same reason, I could really list all model deviations (not to mention it'd be time consuming) such as M1911 and M1911A1 or M1903, M1903A3, etc.
Also, assume that you are limited to ammunition readily available at the time (in other words, no modern expanding ammo).
I can now see why it would have been interesting to leave off the most popular choices, the M1 and the 1911 to see what people would have chosen otherwise.
Oh well, another day, another thread.
