Out of sheer coincidance,I ran into a 4566 in a gun shop today. It was a later one with MIM Hammer and trigger and laser etching instead of roll marks, and decocker only. It had a laser etched message on the right side of the slide which said something to the effect of "decocker lever will return to fire position when released". It also was not a TSW, did not have the rail. Was in nice shape, what do you think something like this is worth? And is it possible to change it from decocker only back to a safety/decocker?
