How can I tell if a barrel is for the 1100 or the 1187 ? I have a 2 3/4" vent rib barrel that seems to be ALMOST identical to the 1100 barrels I have, but there are no stampings designating the model it is supposed to fit. The main diference seems to be on the tang that slides into the receiver, it has 3 tiny holes drilled in it. Normal 1100's don't have these holes, I have 6 other 1100 barrels that I compared this to.
It seems to fit fine, and all the measurements I could take seem to be the same .
Remington cautions about using an 1187 barrel on the 1100 receiver because it can crack the receiver.
 
Where are these drilled holes located? Most 1187 barrels have a gas collar that 1100 models don't have. The word light contour can also indicate an 1187 barrel. Top barrel in pic is an 1187.

Wish it was as straight forward as remington says on their site but it is not. Since the changes they made to slug guns, the 1100 g3's etc
So first what choke system does this unmarked barrel have, fixed, rem choke or pro bore. That will help big time nail it down
Also three gas port holes or just three holes in the tang??? and no markings doesn't sound like a factory remington barrel
Just a comment also I have seen light contour 1100 barrels Darryl but agree there was a time they may have been 1187 only but not any more
Cheers

Here is what remington says but it is not really 100% accurate it seems

In 1987, the new gas compensated Model 11-87 was introduced. While he Model 1100 and the Model 11-87 are similar in design, there are a number of differences which will not allow parts to interchange.

The biggest difference is that barrels are not interchangeable between these models.
The Model 11-87 also has a slightly longer barrel extension. (This is the part that connects directly into the receiver)
The gas cylinders are welded in slightly different locations. This is partly because the Model 11-87 has a longer magazine tube.
The Model 11-87 has 2 gas orifice holes. Only the 2-3/4 inch chambered version of the Model 1100 will have two gas orifice holes while the magnum Model 1100 barrel has only one.

Another difference is in the interchangeability of shotshell lengths.
The Model 1100 can shoot only 2 3/4" or 3" shells depending on the barrel installed. (Always check your barrel for the proper type of ammunition to shoot in it)
Model 11-87 models with magnum barrels can shoot both 2 3/4" and 3" shells interchangeably. To accomplish this, two additional holes are drilled in the top/front of the gas cylinder, and covered with a tempered steel spring. There is a relief cut made into the gas cylinder to accommodate the spring. The Model 1100 gas cylinder will not have the relief cut or the spring.

The barrel in question is a 2 gas port, 2 3/4" fixed full choke, vent rib. The holes in question are not on the gas cylinder / collar area, they are on the barrel extension that goes into the receiver on the beveled edge that runs full length of the extension on the upper side..Comparing this extension length it is the same as my Known 1100 barrels , as is every other measurable dimension . The barrel is clearly marked Remington, and is not an aftrermarket barrel.

Ok. I misunderstood your first post I assumed the no stampings designating the model was no reference to remington also
Well it is not an 1187 barrel or a second generation 1100 with no choke tubes. Sounds like just a standard pre 1987 1100 12 ga 2 3/4 barrel to me
What purpose would these extra holes serve?? None I can think of. I will be honest I cannot remember seeing them in any of mine but never really took the time to look over the years but will watch now the next time I have one apart. I still have quite a few vintage ones to check more than I have fingers and toes lets say
Any chance you can post a pic of the extension/ holes
Cheers

The other barrel is a standard 1100 ,
I would like to be able to use the one with the holes, as it is full choke ,2 3/4", and would handle trap loads well.
I have been shooting 1100's since the 60's and have never seen a barrel like this before.

Ok now I know what you are talking about. I have been shooting them also since 1965 and have seen this before now that I seen the pic or close enough to it
Probally a 30" full choke barrel is it??
Anyway back in the day Remington also played around with drilling holes in the bottom edge of the barrel extension on some factory trap barrels, and mounting a wide, shallow "U" shaped wire which served to narrow the opening for a form of a shell catcher. Worked well, and wasn't as obtrusive as the T & S clip, but also was not easily removable. Only seen a few and only on dedicated Trap guns.
That is what it is IMO

fantastic. THAT EXPLINATION MAKES SENSE. It is a 30", FC 2 3/4" and had a mid bead before someone removed it .Now I just need to replace that mid rib bead. It also has the ivory front bead, like my 20 ga skeet barrel has.
Thanks

Yep . You have a good old factory trap barrel there my friend IMO just less the original wire catcher which is nothing.
take care
