Home Forums Birds & Dogs Shotguns 1100-11-87 differences?????

I am sure this has been asked before, but.....does anyone out there know what the different parts are in these two guns???....I can say for sure that the magazine tube on the 11-87 is stainless steel where the 1100 is blued steel. I know that obviously the chambers in the 11-87 were 3" and the 1100 could be 2 3/4" or 3". Things like checkering patterns aside, or other differences that won't stop an interchange of parts. Thanks in advance for any info!!!

The o-ring groove on 11-87 magazine tubes are in slightly different positions, "most" of the time the 1100 and 11-87 barrels will work, but sometimes there is tolerance stacking and they will not function.

The only parts that are different are the barrels, fore-ends, magazine spring retainers and and magazine caps.

Pre-1987 1100's use a pin integral to the fore-end to lock the magazine cap. 11-87 and post-1987 1100s use the magazine spring-plug to lock the magazine cap.

Early 11-87 fore-ends are shaped to fit the stepped gas cylinder on 11-87 barrels and they will not seat all the way on 1100 barrels.

Later 1187 and post-1987 1100 fore-ends will usually work on pre-1987 1100's, but the magazine caps wont stay tight.

1187's and post-1987 1100's may have "standard/heavy" barrels of "light or Target" contour barrels. The Fore-ends are shaped to match the barrels. A standard fore-end will work, ie with a gap around the barrel, but a "light" contour fore-end will not work on a "standard" barrel.

Thank you sir!!!!!!!! It is greatly appreciated!!!!!! M

You forgot the extractors.. 1100 extractors are narrower than the 11-87s.. Also, the 1100 didn't have an interceptor latch, post or retaining ring... There's a few others too, but my feeble memory is failing at the moment...

Tis true, I forgot the 11-87 extractor is thicker. The post-1987 1100's also us the thick extractor. Pre-1987 1100's and 870's use the thin extractor.


All 1100's and 11-87's have a interceptor latch, post and retaining ring. I thick you are thinking about 870's?

The main difference is the ability to run 2-3/4 and 3 inch with no changes. The 11-87 barrel has a gas collar that the 1100 does not have so even light target loads will cycle reliably. 11-87 also has a stainless mag tube. You can also get light contour barrels for the 11-87.

Damn... Failed memory again.. I just checked the Rem manuals and you're correct...

At the same time, I still don't recall an 1100 having an interceptor latch..

My bad..

You boys know certainly know those Remington autoloaders. I never knew the two models were that different. Good information!

If you are load only 2 shells (ie. clay targets), one in the barrel one in the magazine tube, both the 1100 and 11-87 will function just fine without a shell latch. But, if loading more than one shell in the magazine tube, without a intercepter latch there is nothing to stop the second shell from following the first one out of the magazine and binding up the action.
