Thanks Der. That's how they work. Seems quite awkward to have to pull my hands either off the forearm or off the grip to get my thumb behind the front trigger to set it, but I guess that's the way it was built unless it is supposed to set with a lot less forward pressure than it does now. I wonder how the front trigger can be safely unset? The gold cocking indicator pin for the left barrel does not come up like the other two, and it looks like the tip of the firing pin is missing. Incidentally, one of the reasons I sold my Valmet was in one day sending a load of No. 4 lead at a deer and then whistling a 165 gr. Core-Lokt .30 cal. at a pheasant!

Thanks Miller for the great explanation of the plug gage concept.
