Shotguns are curious weapons. While they are possessed of limited capacity and are a pain to reload with any kind of speed, they have a number of useful features. While they were terrifyingly deadly in the trenches of World War 1, these days they tend to be specialized weapons, often using breaching rounds. Let’s talk about some of the different kinds of rounds one might want to shoot through a shotgun in a military context, and then we’ll talk models of boomstick.
Everyone’s favorite close-range manstopping load. Contrary to popular belief, you do need to aim with buckshot, and it will not send a man flying. Seeing as it consists of 9 pellets, each about .33″ in diameter, it will do an excellent job of ruining a man’s day.
Hunters know there are a lot of fancy slugs out there for specialized purposes. The military guys tend to stick with pretty boring slugs. They’re still 0.72″ in diameter, and they’re absolutely great for wrecking stuff.
While buckshot and slugs can be used to smash the daylights out of hinges and locks, there’s a significant ricochet hazard. Breaching rounds are made from sintered metal pressed together, and are designed to safely destroy door hinges or locks with no risk of ricochet injuries.
Now, let’s get on to the guns themselves, and bring up Questions of Procurement. Let’s first note the obvious absence above: there are no “less lethal” rounds listed. This is notable mostly because it drives the constraints on our firearms. “Less lethal” rounds like beanbag rounds and rubber bullets don’t have enough of a propellant charge to reliably cycle most semiautomatic shotguns. The semiautomatic shotgun would then have to be manually cycled. While this is doable, if this is a key consideration then a pump-action shotgun is going to work better.
With any manually-operated shotgun, the onus is on the operator to not screw it up, and this is annoyingly easy to do. In general, absent a strong need to run less-lethal loads or a very severe budget restriction, the semiauto shotgun is the better choice, because it means there’s one less thing for the shooter to think about. There are few enough shotguns on the market that it suffices to ask a few more features questions, and that will determine our weapon.
First, let’s look at operating systems. Semiautomatic shotguns are either inertia-driven or gas-operated. Both can be reliable if well made. The simplicity and lighter weight of the inertia-driven options make them extremely popular with sportsmen. However, inertia-driven shotguns have the weight of the gun as one of the key parameters for their operation. So, adding weight to that gun, say by adding the lights, lasers, and optics that usually come on military weapons, can make them less reliable. For this reason, we’ll stick to gas-operated models.
Let’s next talk of magazines. Due to the nature of the (usually plastic) shotgun shells, making a reliable detachable box magazine fed shotgun is tricky. There are some who do it right now, namely Saiga and Molot.1 Both of these are Russian, and we run into the usual issues of NATO and politics. We might also expect Remington and Mossberg to introduce some new models of their respective Versamax and 930 shotguns to take advantage of the detachable box magazines which they have introduced on their respective model 870 and 590 pump-action shotguns. However, these are not yet out, and we in the Borgundian War department do not like to be beta testers. I would also honestly wonder if a more traditional, integral, tubular magazine fed shotgun would not be preferred for its extra handiness, since the shotgun is a specialized secondary weapon in military service.
Given the above, the choice is pretty obvious: the Benelli M4 (known in US Service as the M1014). It is highly reliable and tolerates long firing schedules and the general abuse of service well. We will make a few further catalog stipulations. Specifically, we’d like to opt for the M4 Entry model and the factory, three-position, collapsible stock. The three-position stock allows for easier use for those wearing body armor. The Entry model has a 14″ barrel, instead of the 18.5″ barrel on the standard model. Given that the shotgun is a secondary weapon, and the breacher also carries a carbine, we would expect the reduced weight and length to be preferable. Postulating a magazine tube of equal length to the barrel, this will also reduce capacity from 7+1 to 5+1. Again, because this is a secondary weapon used for special purposes, the loss of capacity is not a major issue.
- Of the two, Molot seems to have better QC. In both cases, competition shooters tend to tune the guns extensively, though a good deal of that is due to wanting to run their shotguns with the cheapest ammunition in Walmart. ↩
