Just saw this thread, I'll try to find a pic of mine, but would like to note that on mine, the firing pin protrudes through the recoils shield, so it has to have the hammer resting on an empty chamber, which makes it a "four shooter".. Haven't read all the posts yet, so someone may have addressed this. Looking at your photos m it looks like yours may do this as well.

Best Regards, Les
