When the Remington Model 31A "Standard" Grade was introduced, it was as a 12-gauge 3-shot pump gun with a checkered stock and forearm --
Five shot versions and the 16- and 20-gauges followed fairly soon. Remington did some redesign and introduced the 1934 version which had, to my mind, a rather unimpressive takedown system --
For 1937, Remington introduced the Model 31AP "Standard" Grade with a plain stock and ringed forearm at $42.50 list price, and what had been the Model 31A "Standard" Grade became the Model 31AC "Standard" Grade with the checkered stock and forearm at $45.50 list price. By 1938 the Model 31AC "Standard" Grade was gone and the Model 31AP "Standard" Grade was up to $42.95. By 1939 they dropped the P and the Model 31A "Standard" Grade now had a plain stock and ringed forearm.
In 1941, the Model 31 came of age with the introduction of the 1941 version, with to my mind a much better take-down system than the spring-loded 1934 version, and the larger trigger group giving a better feeling grip. 1941 version on right --
Remington also introduced the lightweight version with the Aeromet receiver in 12-gauge in 1941, but by the June 1941 catalogues they said "Delivries of this model delayed indefinately due to raw material shortage." No mention of the lightweight version in the January 1942 catalogue. By 1947 the Model 31 was again being offered in regular and light weight versions. Model 31LA above and Model 31A below --
