That's an argument I've heard before, and I'm sure there are cases where a good guy's life has been saved by the bad guy not knowing how to operate the gun they just grabbed. But, of all the reasons to have a TS, that's the one that makes least sense to me. Making my gun work for me under the widest range of conditions seems vastly more important.
I'm curious what our SMEs think... @BehindBlueI's, @SouthNarc, anyone else?
