Excerpt from this Guide:
Model 1100
In 1967, the Remington Model 1100
forever changed the way American shooters viewed autoloading shotguns.
It was the first autoloader to combine the repeat-shot versatility of
early-century models with the sleek, modern lines and handling qualities
of revered double barrels. It’s been a field-proven favorite ever since.
Its superb balance, handling, durability and soft recoil from the gas
operated action are the foundation of the Remington autoloading legacy.
In 2004, Remington added a new 20-gauge model in the Classic Field
design.
Model 11-87: RELIABILITY WITH
3 1/2 " CAPABILITY.
In 1987, Remington introduced the
Model 11-87. The unmatched versatility of the Model 11-87 Super Magnum
results from the unique metering system of its patented gas-operated
action. With 2 3/4" field loads, an integral pressure relief valve
remains closed, utilizing all of the shell’s pressure to operate the
action. When heavier shells are used, the valve opens proportionately to
release the unneeded pressure – retaining just the right amount to
operate the action. This not only assures reliable handling of all shell
sizes, but prevents excessive bolt velocity that could increase wear.
Cumulative production total for the Remington 1100 and 11-87 exceeds 4.5
million.
