I've heard two versions of how this 4566 came about.

Version 1: A law enforcement agency in New England ordered them for their maritime patrol.

Version 2: The US Marshall Service ordered them for their fugitive task force.

The pistol is a Melonited 4566 with night sights. No stupid rail on the dust cover either. The three letter prefix on all the ones I've seen starts with R, and apparently all were made in mid to late 2000's.

One member here claimed that the two he aquired had Briley bushings. I never saw any with Briley bushings, and the S&W factory had no information on that.

Anyone know the real story on these? As of spring 2006 S&W still had a few in their vault. My dealer said they would ship him one.....for $900+

I passed. Glad I did. I just located a NIB example for much less.

If anyone has one of these please post a pic. Thanks! Regards 18DAI.
