Hi Fox. I have the exact same pistol (no hold open on last shot) and it has a full travel, firing pin and not designed to be dry-fired. As was mentioned, the odd time, probably won't hurt. Your idea of putting a dummy round in first is a good one - or you could do like me and have new shooters only load 5 rounds. Easier to keep track of 5 than 10, particularly for new shooters - their excitement level tends to screw up their concentration and ability to multi-task - like sighting and trigger control and counting. I'm always standing right beside them and I count too - if they're still holding on target and getting ready to take their next shot, after they've done 5 - give a light smack on the head and tell them, the gun is empty.
