Hello All

Have looked around and finally taken the plunge to join have to say I am new to Remington Shotguns...Have a lot of Browning's but I just picked up my first Remington 1100 used and I need some help so I figure go to those who know.

As stated it is a 1100 20 Gauge serial number 149XX1X it has a non vent rib modified barrel, A release trigger, Wood is in good shape bluing is about 85% no pitting barrel is straight.

So I guess my first question would be what year was she made, Are parts ie: Barrels, Triggers etc. available for what ever model this is I have read that there is a 20 gauge LT & LW can't figure out what this one is.
The guy I bought her from shot trap with her and she wears a Pachmayer trap recoil pad. That is about all I can figure out. I paid $325.00 for her she shoots great but I would like to get a different barrel (Mirages sucked) and loose the release trigger (Just not my thing)

Thank You in advance for any information that you guys/gals could provide to this Remington Newbie.

You can check the serial number Letter Prefix for a general idea of when it was made and the serial number Letter Suffix for what it is.

For instance.....see red highlights below.....
You do not show a Prefix letter in the serial number you gave so this means that your gun was made sometime between 1963 - 1968 because in 1968 Remington added a "L" to the front of serial numbers, "M" in 1974, "N" in 1978, "P" in 1985, and "R" in 1990......still using "R" by the way.

The "X" you show at end "Suffix Letter" of the serial number you give, if truly a "X" and not you being silly and messing with us to hide your serial number for some unknown reason; means that your gun is a 20 gauge "Heavy Frame". This type of 1100 was the first ones offered in 20 gauge and were built on the original 12 gauge frame. They have been discontinued for over 30 years and while some replacement parts are very hard to find, (such as the shell latch) everything you will need can be easily found including a normal trigger.

Another way to drill the age of the gun on down is to check the two letter Date Code that will be stamped on the left side of the barrel closest to the receiver.

KEEP IN MIND that many times barrels on 1100 and 870's get changed and or swapped.

Using barrel codes (such as those listed above) to date the manufacture are reliable on Remington rifles, as the company rarely changed barrels on a customer's rifle.

Using these barrel codes to date a shotgun is somewhat unreliable, as shotgun barrels are often interchanged at random. One needs to be sure that the barrel is original to the gun before trusting the Barrel Code listing, above.

(*) On 8/9/99, stopped stamping the barrels with the date code. They continued to mark the date code on the end flap of the shipping box. They resumed stamping the date code on the barrel on 10/1/01.

Those old Standard weight 20s are still popular with the target set. You can probably sell that trigger group easily, or at least swap it for a standard one plus a few $s. Vent rib barrels are available, but come dear. Good luck.
