Remington 1100 vs. 11-87: Gas Systems Compared
The Remington 1100 and 11-87 are among the best-known American semi-automatic shotguns. Both use a gas-operated action, feed from a tubular magazine, and cycle the next shell automatically after each shot. Their shared layout can make them appear nearly identical, yet the gas systems give each model a distinct operating character.
The main difference is load flexibility. The 1100 was developed around a specific shell-length and pressure range, while the 11-87 introduced a pressure-compensating system designed to handle both lighter target ammunition and more powerful hunting loads. That distinction affects recoil, reliability, maintenance, and the best role for each shotgun.
Understanding how gas is redirected from the barrel into the operating system makes the comparison easier. It also helps buyers choose between a classic 1100, a versatile 11-87, or a specialized variant designed for a particular gauge or hunting application.
Gas-System Architecture
Both shotguns use propellant gas tapped through ports in the barrel. After the shot is fired, a portion of that gas moves into the gas cylinder beneath the barrel. The expanding gas drives a piston and operating components rearward, extracting and ejecting the spent shell. The return spring then moves the bolt forward, stripping a fresh round from the magazine and locking it into battery.
The 1100 uses a comparatively straightforward gas system calibrated for the ammunition class associated with its barrel and model configuration. Standard versions are commonly associated with 2¾-inch shells, while dedicated Magnum versions were built for heavier 3-inch loads. Matching the barrel and receiver configuration to the intended ammunition is important because the system is not infinitely adaptable.
The 11-87 added a pressure-compensating arrangement. Its gas system can bleed or regulate pressure differently as load intensity changes, allowing one shotgun to cycle a broader range of shells. This is the central mechanical distinction between the two models and the reason the 11-87 is often viewed as the more flexible choice.
Cycling and Load Range
With suitable ammunition, both actions can cycle rapidly and smoothly. The 1100 is especially well regarded with standard target loads because its operating system has a long record of reliable performance when the gas ports, piston components, seals, and action parts are clean and in good condition.
The 11-87 is better suited to shooters who move between light field or target ammunition and heavier hunting loads. Its pressure-compensating system helps prevent excessive gas energy with powerful shells while still providing enough force for lighter loads. Actual performance still depends on gauge, barrel length, ammunition, cleanliness, and the condition of the gas seals.
| Feature | Remington 1100 | Remington 11-87 |
|---|---|---|
| Operating type | Gas-operated semi-automatic | Gas-operated semi-automatic |
| Primary design emphasis | Smooth cycling with matched ammunition | Broader ammunition flexibility |
| Typical shell compatibility | Often configured for a specific load class | Commonly supports light and heavy loads in one configuration |
| Gas regulation | Model and barrel dependent | Pressure-compensating system |
| Recoil character | Soft and consistent with suitable loads | Soft, with wider load adaptability |
| Maintenance focus | Gas ports, piston parts, seals, action components | Gas ports, pressure-compensating parts, seals, action components |
| Best-known role | Target shooting, field use, classic ownership | Mixed hunting, clay shooting, and general-purpose use |
Recoil and Handling
Gas operation reduces felt recoil by using some firing energy to cycle the action. The 1100 has earned a strong reputation for a soft, rolling recoil impulse, particularly with 2¾-inch target ammunition. This makes it comfortable for extended clay sessions and for shooters who prefer a stable, predictable swing.
The 11-87 offers a similar recoil advantage, though its handling can vary with barrel length, stock dimensions, gauge, and load selection. When firing heavier hunting shells, the pressure-compensating system helps moderate the action’s response, but a 3-inch shell will still generate more recoil than a light target load.
Balance is another practical consideration. A longer-barreled 1100 or 11-87 may feel smooth and deliberate on crossing targets, while a shorter field barrel can be quicker in dense cover. The right choice depends as much on fit and intended use as on the internal gas design.
Maintenance and Reliability
Gas-operated shotguns require more routine attention than many manually operated designs because combustion residue enters the gas system. On an 1100, carbon buildup around the barrel ports, piston, piston seal, and related components can reduce cycling reliability. A damaged or incorrectly installed O-ring can have a similar effect.
The 11-87 also needs regular cleaning, with additional attention to its pressure-compensating components. The regulating parts must move freely, and the seals should be inspected for wear. Using the correct replacement components matters because small differences in seal condition or assembly can affect how the shotgun handles pressure.
A sensible maintenance routine includes unloading the firearm, confirming it is safe, removing the barrel and operating components according to the owner’s manual, and cleaning residue before it hardens. Lubrication should be light and applied only where specified. Excess oil can collect fouling and slow the action rather than improve it.
Choosing by Use Case
The 1100 remains an attractive option for clay shooters, upland hunters, and collectors who value a proven design with a familiar operating feel. A properly configured 1100 can be exceptionally smooth, and its long production history means that many replacement and upgrade parts are available through established firearms channels.
The 11-87 makes more sense for someone who wants one semi-auto shotgun for several roles. Its broader load range can simplify a season that includes light target shells, field loads, and heavier waterfowl or turkey ammunition, provided the specific model is rated for the intended shells. Browse the Remington shotgun catalog to compare current configurations, gauges, barrel lengths, and chamber specifications.
- Choose an 1100 when smooth target performance and classic design are the priorities.
- Choose an 11-87 when ammunition flexibility is more important than a simpler configuration.
- Confirm chamber length, gauge, barrel markings, and approved ammunition before purchasing.
- Give stock fit and balance equal weight with gas-system features.
- Budget for seals, cleaning supplies, and periodic inspection of operating parts.
Model Details and Setup Checks
Model names alone do not tell the entire story. Remington produced numerous 1100 and 11-87 variants, including different gauges, chamber lengths, barrel profiles, stock materials, and specialized hunting or competition configurations. Two shotguns with the same family name may therefore have different ammunition limitations and handling characteristics.
Before buying a used example, inspect the barrel ports, gas-cylinder area, piston components, O-ring, magazine tube, bolt, and receiver for corrosion or excessive wear. Check that the barrel and forend fit correctly and that the safety and trigger function properly. A qualified gunsmith should evaluate any firearm with questionable parts, damage, or uncertain history.
Buyers considering several firearm types can also review the store’s rifle selection when comparing a semi-auto shotgun with a rifle for a different hunting role. Regardless of platform, verify local laws, transfer procedures, and the receiving FFL’s requirements before placing an order.
The 1100 and 11-87 share a dependable gas-operated foundation, but their priorities differ. The 1100 is the classic choice for a matched, soft-shooting setup, while the 11-87 offers greater flexibility across ammunition types. Review the specifications carefully, select the model that fits your intended use, and place your order through a reputable Remington firearms retailer with the correct FFL and shipping details.
