I used a Ruger P85. It didn't matter if I shot the first round in SA or DA. We had to show proficiency with the firearm that we selected. My only other choice at the time was my 738 TCP. I too am a bit surprised that there is a distinction between revolver and semi-auto. Strange. I'm also a bit surprised by the number of states that don't require applicants to fire one shot. I guess that just comes down to each state's prerogative.
