Notes: Very similar to the Remington 11R, the Savage 720 is also an American copy of the Browning Auto-5M. It was not marketed to police departments, but was meant to be a military shotgun. However, the US military never bought the Savage 720 in quantity, and today it is a rare find.

Notes: The SAS (Semi-Automatic Shotgun) is the descendant of such Weatherby shotguns as the Centurion, Centurion II, and Eighty-Two. The SAS is built for Weatherby by Valtro of Italy (who also makes and sells a similar shotgun, the A930 SL). It was introduced in 1999. The SAS is operated by a self-regulating gas system which allows the shooter to fire many different types and loadings of cartridges. The stock contains a shock absorber to take up some of the recoil, and in addition, the butt has a thick recoil pad. The trigger mechanism may be removed from the weapon in one piece for maintenance (though it is not adjustable. The bolt catch incorporates a mechanism to cut off feed from the tubular magazine so that special rounds may be fired without emptying the magazine. The barrel wears a hard chrome lining. Above the barrel is a ventilated sighting rib which also contributes to head dispersion. The SAS at the time of introduction was available with a wooden or plastic stock (the latter in black or camouflage), but the line was revised in 2002, with separate sub-models being introduced with a synthetic stock. The chamber may take 3-inch or 2.75-inch shells. The SAS is sold with Briley IMC interchangeable chokes, and has a receiver made from aircraft aluminum. Up to three spacer rings may be placed between the receiver housing and stock to allow the length of the stock to be varied somewhat. They can also angle the stock somewhat to suit the shooter. There are several versions of the SAS.

SAS camouflage versions come in dark leaf pattern known as Break-Up or a straw motif known as Shadow Grass. The stocks are synthetic and overprinted with the camouflage pattern. The interchangeable chokes which come with the guns are Full, Modified, and Extra Full for the Break-Up or Modified, Improved Cylinder, and Skeet for the Shadow Grass. The two come in slightly different barrel lengths. The sighting rib is tipped with a special high-contrast plastic tube bead.

The SAS Field and Synthetic versions differ only in the stocks; the Field has walnut stock, while the Synthetic has a stock of matte black high-impact plastic. They have the same weight and use the same barrel lengths. They come with interchangeable chokes of Improved Cylinder, Modified, and Full.

The SAS Sporting Clays shotgun is designed not only for clays, but for fowling. The stock is walnut, and the barrels are the longest of the range. The interchangeable chokes supplied are Full, Modified, Improved Cylinder, and a pair of special Skeet chokes known as SC I and SC II.

Twilight 2000 Notes: The SAS does not exist in the Twilight 2000 timeline.

Notes: Like Remington did with its Models 870 and 1100, Winchester decided to make a semiautomatic sister weapon to its Model 1200 in 1965, the Model 1400. The Model 1400 was designed to have as many parts in common as possible with the Model 1200, and to use the same barrel lengths and gauges of ammunition. However, the design of the Model 1400 did not allow for simple tubular magazine extensions – and this made making a military version (not to mention increasing the ammunition supply easily in civilian models) quite difficult. (Extended tubular magazines do exist for the civilian versions, but they are very rare.) This is primarily because the gas operation of the Model 1400 operated from the inside of the end of the tubular magazine, and therefore extended magazines would have to be specially-made for each length of magazine.

It took close to a year to overcome this problem. Winchester "fixed" the problem by simply doing away with the tubular magazine feed, and replacing it with a box-magazine feed. A sleeve was added in front of the trigger group, and the loading port for the tubular magazine became the rest of the magazine well. The ejection port was enlarged. Originally, modified M-14 magazines were used to feed the Model 1400, but these proved unreliable and new curved magazines were designed. There were more teething problems. The action of the box-fed version functioned so fast that the shells often could not rise into the chamber quickly enough, resulting in jams. This problem was solved by adding a special bolt catch, but this also increased the complexity of the Model 1400.

About this time (late 1966), the US Marine Corps was looking for a new semiautomatic combat shotgun, and Winchester decided to enter the Model 1400 into the competition. Unfortunately, the relative complexity of the Model 1400 Combat version and the fact that undisclosed bugs kept popping up meant that the Model 1400 was prone to stoppages for all sorts of reasons, especially when dirty or abused. The long 23-inch barrel was also frowned upon by the Marines. Winchester objected to what they called the harshness of the testing process, but it was in fact no different from that of any other small arms. Winchester then tried to shop the design to the Army. The Army agreed that it was a promising weapon, if it was just developed more, and the Army wasn’t willing to fund such development. In 1969, work on the Model 1400 Combat was stopped, never to be continued. The Winchester 1400 Combat is now a very item to find indeed, and most of the prototypes are in storage or on display at Winchester or in US military museums and arsenals.

The Model 1400 Sporting (civilian) version continued on for a few more years, but eventually it too was discontinued, even though it did not have the problems of the Model 1400 Combat.

Construction of the Model 1400 consisted of wooden furniture, an aircraft aluminum receiver and magazine, and other metalwork of steel. The tubular magazine of the Sporting version looks big, but much room is taken up by the gas mechanism. Sights range from a ventilated sighting rib to rifle-type sights; the sights of the Combat version were designed to be similar to those of the M-14 rifle.

Notes: This was originally a sporting shotgun based on the Super X. It was introduced in 1999, and is a gas-operated semiautomatic shotgun with a mechanism that automatically compensates for rounds of differing loadings or types. The standard Super X2 comes in Magnum Walnut and Magnum Stalker versions; they are essentially identical, except that the Magnum Walnut model has a walnut stock and fore-end (with a thick recoil pad on the butt) and a standard ventilated sighting rib above the barrel, while the Magnum Stalker uses a black high-impact plastic stock and fore-end and has sight beads on the front and midway down the barrel rib. These two versions have 30-inch barrels and weigh and shoot the same for game purposes. The Hunter Walnut and Hunter Stalker are similar to the Magnum Walnut and Magnum Stalker, but they fire 3-inch shells instead of 3.5-inch shells, and come in three barrel lengths. Another type is the Camo, which is essentially similar to the Hunter Stalker for game purposes with the exception of having no sight beads. These guns use Invector interchangeable chokes.

In 2001, the Super X2 Sporting Clays appeared. This version is similar to the Hunter Walnut, but uses 28 or 30-inch barrels, has back-bored barrels, and has a stock equipped with spacers to allow a more customized fit for the shooter. The stock, fore-end, and metalwork are finished with a low-glare finish. The Sporting Clays is equipped with Invector-Plus interchangeable chokes of five types.

In the same year, Winchester introduced the Practical, which is a high-capacity magnum shotgun designed for police use. This gun has a short 22-inch barrel, an attachment rail for optics, an adjustable rear leaf sight, and a front sight bead with a TruGlo glass fiber insert. It has an extended magazine, and the stock and fore-end are of composites. In 2002, the Practical Mk II appeared, this is essentially similar to the Practical, but the rear sights are interchangeable Ghost Ring or adjustable leaf sight, and the front sight is a TruGlo fiberoptic sight. It also has a cantilever rail based on the Picatinny Rail. It can therefore mount a wide variety of optics, though not as wide a variety as a genuine MIL-STD-1913 rail.

In 2003, the Greenhead was introduced; this version is designed especially for fowling, has 3.5-inch chambers with Invector-Plus interchangeable chokes. It is somewhat heavier than the Magnum Stalker, and uses a synthetic stock colored in a greenish-teal color known as "Greenhead." Also in 2003, the Cantilever Deer was introduced; this version is specially designed for slug throwing, with a short 22-inch barrel, synthetic stock and fore-end, and rifle-type sights, along with a cantilever rail similar to the one used with the Practical Mk II above.

Some new versions to the line are the NWTF Turkey, with a synthetic stock and fore-end, and finished in camouflage of either a "Mossy Oak Obsession" or "Mossy Oak Break-Up" pattern. The barrel is 24 inches long and equipped with a fixed choke of Extra Full. The NWTF Turkey has a ventilated sighting rib equipped with three-dot TruGlo sights on the rib. It can fire shells from 2.75 to 3.5 inches in length.

The Universal Hunter Field is designed to be an all-purpose gun; it fires 3.5-inch shells. The stock and fore-end are synthetic, and the gun is finished in either of the Mossy Oak camouflage patterns. The barrel is 26 inches long, has a sighting rib and is equipped with Invector-Plus interchangeable chokes. The gun has a sling. The Universal Hunter Turkey is essentially the same weapon, but the Invector-Plus chokes include an Extra-Full choke.

The Light Field is just that – a lighter version of the Super X2. Despite the light weight, it still comes with medium and long barrels, and has a walnut stock and fore-end. The barrels use Invector-Plus interchangeable chokes.

Twilight 2000 Notes: None of these shotguns are available in the Twilight 2000 timeline.
