Model: Remington 870
The Remington 870 holds the record for best-selling shotgun in the world. It was first manufactured in 1951 and sales have been steady since, with over 10 million guns having been produced. It's in use with police and military organizations worldwide and is just as popular for hunting, self-defense, and sport shooting.
There are six basic types of 870:
Wingmaster shotguns are blued steel with high gloss or satin walnut stocks.
Police shotguns are blued or parkerized steel with satin walnut or synthetic stocks. All of the parts are heavy-duty and receive extra care and inspections during assembly.
Marine shotguns are nickel-plated with synthetic stocks.
Express shotguns are matte black bead-blasted with laminated hardwood or synthetic stocks, and cheaper.
Super magnum shotguns are chambered for 3 1/2'' 12 gauge shells.
XCS shotguns have TriNyte-coated external metal with nickel-plated internals and speedfeed stocks.
All can be given bead, double bead, ghost ring, or adjustable open sights. All can be given cantilever and receiver mounts for scopes and reflex sights.
Where to find:
As stated above, the shotgun is extremely common worldwide. Police and military forces across the globe make good use of the gun, and it's just as common among civilian households. With over 10 million shotguns, it's not hard to get one. They're available in the majority of firearms shops, especially in the United States, and can be found for less than $300.
Complexity:
Though not a simple as a break open shotgun, the gun is quite simple and has less moving parts than most designs. The controls and action are quite similar to the Remington 7600 series of pump-action rifles, so any shooter familiar with those can quickly learn to operate an 870. There are relatively few controls compared to a handgun of similar cost, and the general format is used on a multitude of other designs.
Size and weight: Weight 112 ounces (3.2 kg) to 128 (3.6 kg) unloaded. Length 946mm to 1,283mm. Barrel 457mm to 762mm.
Action:
Pump-action.
Caliber(s):
12 gauge, 16 gauge, 20 gauge, 28 gauge, or .410
Magazine:
Tubular magazine under the barrel. 3-8 rounds.
Trigger:
6-8 pound pull, can be reduced to 2.5-3.5 pounds by a match grade trigger.
Controls:
Push-button safety behind the trigger (push from the right to fire, push from the left for safe). Slide release, or action release button is to the front right of the trigger, protruding down from the receiver. The slide release is far forward enough that you will need to release your shooting grip to actuate it.
The shell elevator or shell latch is spring loaded on Remington 870s, staying down during loading.
Loading: How to load the firearm and make ready to fire.
Condition One, or "Locked and Cocked." Chamber loaded, magazine full, hammer cocked and safety applied.
1) Point the gun in a safe direction. Critical step in case the gun accidentally discharges! 2) Ensure that the forend is in the fore-most position.
3) Take a shell with the brass end against your thumb.
4) Using the trigger guard as a guide, push the shell up and forward into the loading port until the rim of the shell engages the shell latches.
5) Continue loading until the magazine is full.
6) Firmly rack the forearm all the way to the rear, then forward, to chamber the first round.
7) Apply the safety.
Condition Two. Chamber loaded, magazine full, hammer down, safety off.
Impossible on a pump action shotgun.
Condition Three. Chamber empty, magazine full, hammer down, safety off.1) Point the gun in a safe direction. Critical step in case the gun accidentally discharges! 2) Ensure that the forend is in the fore-most position.
3) Take a shell with the brass end against your thumb.
4) Using the trigger guard as a guide, push the shell up and forward into the loading port until the rim of the shell engages the shell latches.
5) Continue loading until the magazine is full.
Unloading:
1) Point the gun in a safe direction.
2) Depress the action release.
3) Slowly slide the forend back until the front of the shell just clears the forward edge of the ejection port.
4) Remove the shell by hand.
5) Slide the forend all the way back to load the next shell.
6) Turn the shotgun to the right, letting the shell roll out of the ejection port.
7) Press the shell latch on the right side of the receiver to release a shell from the magazine through the loading port.*
8) Continue until the gun is empty.
9) Visually and manually inspect the chamber for any remaining rounds. In low light, feel inside the chamber and magazine tube for shells.
10) Point in a safe direction and pull the trigger. Hammer should snap onto an empty chamber.
*Alternatively, instead of operating the shell latch, the shooter can simply rack the forearm until the weapon is empty.
Field Stripping:
1) Point the gun in a safe direction and unload it.
2) Unscrew the magazine cap by hand. If it gets stuck, wrap it with a cloth and use pliers. Hold onto the cap tightly, as it is spring-loaded and can pop off with force!
3) Slide the barrel off.
4) Flip the shotgun upside-down and press down on the spring-loaded metal strips on the forend from the inside of the opening until they're flat, and pull the forend and bolt carrier out like you did with the barrel.
5) Use a wooden dowel rod or other object the size of the pins (screw, nail, screwdriver, etc.) to tap out the pins on the trigger group. Slide the trigger group out from the bottom.
Reassembly
1) Slide the trigger group back into place and tap the pins back in.
2) Slide the forend in while holding the metal strips down.
3) Slide the barrel back on.
4) Insert the shell follower into the magazine tube, then the spring. Place the magazine cap over the spring and screw it on by hand until it will no longer move. Do not use pliers to screw the magazine cap back on, as the extra torque may damage the gun!

Model: Stoeger Coach Gun
The Stoeger Coach Gun is a double-barreled shotgun marketed by Stoeger Industries in Accokeek, Maryland. It is primarily designed for the sport of cowboy action shooting, though it is also fairly common for home defense, bird hunting, and clay target shooting.
The Coach Gun has several variations. The standard model has fixed chokes, one Improved Cylinder and one Modified, a hardwood or walnut stock and fore-end, and a blued, matte nickel, or polished nickel receiver and barrels. The Coach Gun Supreme has screw-in choke tubes, a recoil pad in the butt, a AA-grade walnut stock and fore-end, and either blued or nickel-plated receivers and barrels. The Double Defense is a modern version made specifically for home defense; it has a black matte finish and two picatinny rails for add-on accessories, such as laser pointers and flashlights, along with an internal hammer, single trigger, and a fixed Improved Cylinder choke.
Where to find:
Being designed for cowboy action shooting, the Coach Gun is one of the most common double-barreled designs out there, especially in states like California where the sport is popular. The standard gun costs close to $400, which is fairly affordable for such a well-made shooting piece.
Complexity:
A double-barreled shotgun is about as simple as you can get, not including single-barreled guns. It has extremely few controls to learn and no complex actions.
Size and weight:
Weight 2.9 kg (6.5 lbs) unloaded. Barrel length 508-610 mm (20-24 in.). Total length 927 mm (36.5 in.)

Model: Remington 1100
The Remington 1100 is a gas-operated semi-automatic shotgun that has been in manufacture since 1963. Since its inception, the 1100 has been the best-selling autoloading shotgun in US history. It was an immediate success with skeet shooters and has found great popularity with hunters and law enforcement.
The 1100, aside from its gas-operated mechanism, is a very standard Remington shotgun and is very easy to use for anyone who has used Remington products before. 47 years later, the 1100 is still in production and still very popular among shotgun users worldwide.
Where to find:
As stated above, the 1100 is the best-selling autoloading shotgun in the United States. Along with its common use in skeet shooting, it is also popular with hunters and law enforcement and is used by the Malaysian Special Operations Forces. It's not particularly cheap, however, at $945 for a base model and going into $1200 for premier pieces.
Complexity:
The 1100 is a highly reliable shotgun and ushered in the age of truly successful and reliable autoloading shotguns. It likely won't jam on you in combat and is not particularly difficult to disassemble. It also shares some parts with the 870 pump-action series.

Model: Mossberg 500
The Mossberg 500 series is one of the most popular shotguns in the world, second only to the Remington 870 series. It is a basic hammerless pump-action shotgun, introduced in 1961 and chambered for 3-inch magnum shells. It has a very large number of optional features that allow for users to customize their shotgun to their liking. The guns can be given various finishes, such as parkerized, matte black, camouflage, or aluminum alloy. The stocks come in wood or composite (matte black or camo). The Mossberg 500 Mariner has a silver Marinecote finish that is highly resistant to corrosion and a matte black stock.
The Mossberg 590 has a different magazine tube design for easier cleaning and parts replacement, but the 500 allows for easier barrel changes. The 590A1 has an aluminum trigger guard and safety (rather than polymer) and a heavier barrel for military use. The Bantam is slightly scaled down for smaller shooters, while the Super Bantam has two recoil pads and a stock spacer. The Model 505 Youth is like the Bantam, but even smaller and only available in 20 gauge or .410 bore. The 500 series can be found in many variants apart from these models, suitable for fowling, military and police uses.
Where to find:
The Mossberg 500 is one of the most common shotguns in the United States, though the 590A1 is a Title II weapon and a bit harder to acquire. As such, the various models and parts are very easy to find.
Complexity:
The Mossberg is a rugged shotgun that does well out in the field while hunting and trekking, though the 590A1 is more suited for rough military use. It can be found for $230-300 in most hunting stores.

Model: Ithaca Model 37
One of the oldest shotguns still in production, the Ithaca has been in continuous production since 1937, with the design dating back to 1933. The 37 uses John Browning's patented bottom ejection system for shells, making it ambidextrous and popular with left-handed shooters. While the introduction of a sporting arm during World War II was not particularly good for sales, the shotgun was used in the Vietnam War by the United States as a powerful, short-range weapon for the jungles of Vietnam.
The Ithaca Model 37 is available in a variety of versions. The Ultralite has an aluminum receiver; the Deerslayer has a short barrel and rifle sights; the DSPS is a police and military version of the Deerslayer; the Stakeout has a 13 inch barrel, pistol grip, and no stock; the 28 Gauge, obviously, is chambered for 28 gauge shells; the Defense is a home defense version with either an 18.5 inch barrel and 5-shell capacity or 20 inch barrel and 8-shell capacity.
Where to find:
The Ithaca Model 37 is one of the most popular pump-action shotguns today, especially for home defense. The Los Angeles Police Department is the single largest buyer after the United States military. The shotguns can be bought for $500-600 brand new, with second-hand guns going for less.
Complexity:
A classic Browning design, the Model 37 is very reliable and simple. With the bottom ejection of shells, the gun can be used by left and right-handed shooters with little difficulty.

Model: Harrington and Richardson Topper. First manufactured in 1893, the Topper is one of the most famous and popular single-shot shotguns of all time. This model is ingrained into the hearts of many as the gun they began hunting with. The simplicity of the gun and inexpensive price has made it very common in America. As of right now, H&R offers four models: The Topper, The Topper Deluxe, The Topper Classic Deluxe, the Topper Junior, and the Topper Junior Classic. Each of these runs the full gamut of options and accessories. Where to Find: Given that it's a single-shot, the Topper isn't used by any law enforcement of military units. However, its extreme popularity as a "first gun" has caused it to inhabit many a cabinet or wall. Also, it's very common in gun shops across America, often for very low prices (i.e. less than $100.) Complexity: Guns literally do not get any simpler than the Topper. It has very few moving parts, and is about as easy to use as any shotgun can be. Size and weight: Varies extensively between models and accessories.
Weight is generally between 5 and 7lbs. (2.26 and 3.17 kg, respectively.) Barrel length can be anywhere from 18" to 32" (457mm to 813mm.) For most models, the OAL is around 43" (109.2 cm.) Action: Single-shot breech-loader. Calibers: 10, 12, 16, 20, 28, .410. Magazine: None. Trigger: Single-action.Controls: Aside from the trigger, this gun only has two controls: the hammer, and the side lever. The lever is located directly to the right of the hammer. Loading: Given that this gun lacks a safety, the traditional "condition" rules do not really apply. However, the method of loading in preparation to fire is:
1.Point the gun in a safe direction. Critical step in case the gun accidentally fires. 2.Push the side lever to open the gun.
3.Insert the shell.
4.Close the gun.
5.Pull back the hammer.
If you wish to render the gun "safe," simply refrain from lowering the hammer. Unloading: 1. Point the gun in a safe direction. Critical step in case the gun accidentally fires. 2. If the hammer is c*cked, lower it (by securing a firm hold on the hammer, pulling the trigger, and gently lowering the hammer down.)
3. Press the side lever.
4. Remove shell.
5. Close chamber. Field-stripping: 1. Point the gun in a safe direction. Critical step in case the gun accidentally fires. 2. Press the side lever..
3. Remove shell.
4. Remove screw in fore-end.
5. Remove fore-end.
6.Press the side lever, and remove the barrel. Design Quirks: Nothing except for the fact that there is no safety. The Rules - What you should know before reading these pages and handling weapons.
