Ok, Remington 870 Police is very cool, it is the top level Remington 870 shotgun but it is also more expensive. Also, if you are not in US, it could be difficult to find the Remington 870 Police version. Remington 870 Express shotguns are more common and easier to find around the world. They are good too but they lack some features of the Model 870 Police. They are available separately and you can easily buy and install them on your Model 870 Express.

Remington 870 Police is believed to be more reliable and sturdy than Remington 870 Express shotgun. Let’s see how you can upgrade your Remington 870 Express. Upgrades are not as expensive as you may think. Also, they are pretty easy to install without help of a gunsmith. You can easily do everything at home.

Here are 10 steps to upgrade your Remington 870 Express to Police version…

Step 1, Selecting a Good Remington 870

Check the Remington 870 you are going to buy. Take snap caps with you and check if everything is good when loading shells into magazine tube. Check extractor and ejector. Make sure that shotgun extracts all shells reliably. Check finish of the shotgun, look for scratches or rust. Disassemble shotgun and check barrel, it is very important to check chamber, it should not have marks, it should be smooth. Inspect all parts. Look into the barrel, use flashlight if needed. Check for scratches and pitting inside of the barrel of a shotgun. Notice the condition of a recoil pad, stock, forend, sights.

Step 2, Upgrading Magazine Spring

Remington 870 Police guns have a longer magazine spring, so we need a better one which ensures positive feed and function. The best magazine spring available for Remington 870 is Nordic Components magazine spring. Don’t look no further, I’ve checked many of them and there is no spring better. You will have to cut the magazine spring to proper length. I recommend having several spare springs.

Some of the shooters prefer Wolff magazine springs which are good too.
