Received a 4566 TSW today which I bought on Gunbroker. Very nice condition, two factory mags with black followers and a blue case that originally belonged to another Gen lll gun. It seems it is a "decocker", which I didn't realize when I bought it. It has the caution label on the right side of the slide. Contrary to what I've read here on the forum, it also has a dot of red paint which shows when the decocker is in the up position.

Haven't fired it yet, though I was at the range when I picked it up. Guess I'll have that to look forward to next week. Range report and pics to follow.

As a dyed in the wool revolver guy, I somehow have managed to accumulate a 1006, a 4006, and now the 4566 all in the space of about six weeks! Yeah, I'm looking for a 5906 to round out the collection.
