About the Gun

The model number 520 was used on two completely different revolvers produced 25 years apart. Since they share the same model number they are represented here as model variants. The first variant was originally designed in 1997 at the request of the New York State Police who were considering changing from the K-frame fixed sight Magnums to a similar gun in the N-frame size. About 3,000 were produced but in the end were not sold to the State Police. They were ultimately offered to the commercial market as the model 520. The second variant was introduced in 2005, and except for its barrel length, overall length and frame finish has nothing else in common with the original model 520. It is a 7-shot revolver built on an L-frame with a titanium cylinder.

Production

Production of this firearm began in 1977 and continued until 1983. It was part of a limited run based on an earlier design, with manufacturing taking place during that specific six-year period before being discontinued.

Analysis

This .357 Magnum revolver offers a robust design tailored for shooters seeking precision and dependability. Its accuracy is commendable, particularly at moderate ranges, benefiting from a well-balanced frame that aids in consistent shot placement. The ergonomics are thoughtfully executed, with a grip that accommodates a variety of hand sizes, promoting comfort during extended sessions. Reliability is a key asset, as the mechanism functions smoothly under diverse conditions with proper care. However, maintenance can be somewhat demanding, requiring regular attention to prevent wear on internal components. Availability of replacement parts may pose a challenge for some owners, potentially leading to delays in repairs. The trigger pull is crisp, though it might feel heavy for newer shooters, requiring acclimation. Felt recoil is noticeable, especially with full-power loads, which could be a consideration for those sensitive to kickback or lacking experience with magnum calibers.
