Why no 38 special? It's arguably carried just as much any of the other calibers. More than the niche cartridges of 357 Sig or 10mm Auto.

This is a research poll about 5 calibers of semi auto pistols people own and shoot. It is not about revolvers or concealed carry. That is another poll.
I want to know about those 2 niche calibers owned and shot.
