I felt the need to take two of my older models out of their boxes.
Both are Marushin ABS models in metal finish from the late 1980s/early 1990s I'd say.
I bought them both 15 years ago for 150 Euro each.
The real Smith & Wesson Model 39 was the first U.S. designed double action (DA) semi-automatic pistol marketed in the United States. The German Walther P38 DA pistol impressed American ordnance personnel during World War II. The Army Ordnance Corps issued a proposal for an American equivalent to the P38. In 1949, Smith & Wesson began development of the Model 39 chambered in 9×19mm Luger and it entered the market in 1955. This is considered a first generation pistol. Since the Model 39 came out, S&W has continuously developed the design into its third generation pistols now on the market. First generation models use a 2 digit model number, second generation use 3 digits, and third generation models use 4 digits.
The Illinois State Police adopted the Model 39 in 1968. In a time when police was using revolvers in general this helped ingratiate semi-automatic pistols with law enforcement.
A modified version of the Model 39 with a wider grip frame to accommodate a 14-round magazine was used by Naval Special Warfare units during the Vietnam War. It was issued to officers-in-charge (OICs) of MST-2 detachments as their sidearm. SEAL Teams used either the Model 39 without modification or a modified version, the Mk 22 Mod 0, which was called the "hush puppy". The modified pistol had a suppressor with a slide lock (preventing the slide from moving backwards upon firing, thereby decreasing produced noise). The Mk 22 Mod 0 had raised iron sights, to provide easier sighting over a bulky suppressor. The gun's purpose was to eliminate sentry dogs or guards without alarming the main target.
I could not find much information about the M439, but this model has obviously different adjustable sights.
The single stack magazine looks very similar to a Walther P38 magazine.
The safety is also working as a decocking lever.
The metal finish looks nice but wears off quickly. I am not sure about the plastic grips, but the colour looks okay I'd say.
Both models do not feel too light for a ABS model (450 g unloaded).
Note the slide on the M439 has "J.S.A." instead of "U.S.A" on it.
