Remington 870/1100 Non-MIM (Machined) Extractor
One of the simplest ways to improve your shotgun’s performance is to change a standard MIM (Metal injection molded) extractor with non-MIM (solid steel) extractor. Steel extractors are used on the Remington 870 Police shotguns because they are more durable and allow heavy use of a shotgun.
An extractor is a part found in most firearms. It removes the spent cases from the ammunition that gets fired after you pull the trigger. With Remington 870/1100 extractors, you can use a non-MIM or a MIM extractor for the shotgun. MIM stands for metal injection molding. Newer Remington 870/1100 shotguns use MIM extractor. But the good news is that you can replace the MIM extractor with a Non-MIM extractor.
Non-MIM extractor, which is commonly referred to as a “machined extractor,” is an upgrade for the Remington 870/1100 that many gun owners are more comfortable with. The Non-MIM is known for insuring that fired shells get extracted properly and without any problems. A big complaint people make about the MIM extractor is that it breaks too easily and that it is unreliable.
For anyone who owns a Remington 870, it won’t cost a lot of money to replace the MIM extractor if it breaks off. The non-MIM extractor is very inexpensive and easily to install as an upgrade for your weapon. It will also make the extraction of fired shells much more reliable in your weapon than it did with the MIM extractor.
If you look at the police version of the Remington 870 shotguns these days, they all have non-MIM extractors in them because of their reliability. For all gun owners who still have a MIM extractor in their Remington 870 and find it unreliable, it will only cost you around $15 to replace the MIM with a non-MIM. This is one of the best and most cost effective investments you can make in preserving the quality and reliability of your Remington 870.
Non-MIM or Machined Extractor
Machined extractor is one of the must-have upgrades for your Remington 870/1100. It insures reliable extraction of fired shells. Police version of the Remington 870 utilizes non-MIM extractor too because it is more reliable.
If your Remington 870/1100 has problems with extraction – changing extractor is the first procedure you need to do. This upgrade is not for looks it is for reliability. Better non-MIM extractor costs just $14.99 but improves your shotgun dramatically.
Non-MIM extractor is my first recommendation to Remington 870 owners which starts upgrading their shotguns. Most shooters spend hundreds of dollars on tacticool upgrades but rarely upgrade inner parts. This is one of the cheapest but the most important upgrades you can make to Remington 870 shotgun

Non-MIM, solid steel extractor is better than MIM extractor. Solid steel is more wearproof than stamped metal. When extractor hook begins to round off, you can have problems with extraction of fired shells.

When you fire a Remington 870/1100, or any other type of shotgun, you will see the shells fall out of the chamber onto the ground. The part of the shotgun that removes shell after it is fired is called the extractor. Once you cycle the action of the gun, the shell is removed from the firing chamber. It is important to have a durable extractor if you use your shotgun a lot. Most Remington 870/1100 shotgun models come with a metal injection molded extractor which is good for standard use only. But if you are someone who goes shooting a lot then you will want a solid steel extractor in your shotgun instead. These extractors are typically found in Remington 870 Police models since law enforcement officials tend to shoot shotguns more often than civilians. However, this doesn’t mean you can’t install a solid steel extractor into your Remington 870 to make it more reliable.
To replace your existing extractor, first, make sure your Remington 870/1100 is not loaded with any ammunition. Double check the chamber and magazine tube to ensure that there is no ammunition. After that, disassemble the shotgun and take out the bolt. Take a flat headed screwdriver and put it between the extractor and the plunger. Pull the extractor back with the screwdriver until the spring behind it is depressed. Now you can lift out the extractor by rotating it until it comes out. Now take your new steel extractor and push it in by rotating it until you hear the extractor snap into place. At this point, you can reassemble the rest of the shotgun by reversing the process you just went through.
Video: Changing Remington 870/1100 Extractor (MIM or Non-MIM):
Solid steel extractors can be purchased at most gun stores for about $25. You might see them advertised as non-MIM, or non-metal injection molded. This just indicates that it is not the standard metal injection molded extractor that usually comes with the Remington 870/1100. But just to be safe, ensure that the extractor you purchase is in fact solid steel because this is the best extractor you can get. After you have installed the extractor, you should go test your shotgun at some targets in order to see how well the shells get extracted. If you don’t notice any problems then you have successfully upgraded your shotgun with the new extractor. But if you do notice problems, then disassemble it again and check to make sure all of the parts were put back correctly.
