The general cosensus is from those I have read, from folks here, from folks on other forums, from LEO's and from those who teach. Now I will agree that there is not a vote that I know of but that is where I got my info from.
Generally, from what I read, a semi, being flatter, can be held closer to the body and therefore less printing. I don't think that applies to all semi's cause some of the double stacked weapons are pretty thick.
Now I carry without a scabbard most of tha time, in a pocket, but there is a few tricks to that.
