Our Assessment: The Smith & Wesson Model 520 is one of the rarest and most collectible N-frame revolvers ever made. Originally developed at the request of the New York State Police in 1979, this model was designed as a heavy-duty fixed-sight service revolver chambered in .357 Magnum. When the NYSP decided to go with the adjustable-sight Model 28 instead, Smith & Wesson completed the run of 3,000 units and sold them commercially in 1980. These revolvers were never cataloged, making them a limited production item right from the start.
This example, serial number N560382, is in exceptional condition with 99% of its original finish remaining, sharp stocks, and a matching factory box. The included factory letter and period literature provide excellent provenance and confirm the significance of this model. Mechanically sound and beautifully preserved, this is exactly the kind of revolver advanced S&W collectors look for—scarce, correct, and complete.
The Model 520 offers a perfect combination of function, rarity, and law enforcement heritage. For collectors seeking a centerpiece N-frame with limited production and a fascinating backstory, this revolver checks every box. So bid high and bid firm. I highly recommend that you review the item’s condition using our high-quality photos. Good luck with your bid. -K.F.
