Special thanks to RomeoPapa for posting pic of the ISS (J-lock safety) of Remington 870 on Remington 870 Forum:
Here ya go. As shown, with the pointer aligned with the white dot, the safety cannot be moved to the “fire” position. You have to insert the key (the green thing) into the “J” shaped opening and rotate the pointer to the red dot. You can then take the safety off.
Safety flag is inexpensive but very useful tool. Chamber safety flag shows others that your shotgun is unloaded and chamber is empty. That makes everybody comfortable.
Safety flags are mandatory on competitions of a high level and with big number of competitors. You can carry your shotgun ONLY with safety flag installed.
Tapco Shotgun Chamber Safety Flag is made of bright polymer composite. It fits into the chamber of a shotgun perfectly. Very simple and useful tool. I recommend having several spare flags because they can get lost and you will have to buy one on the range (where they sold at ridiculously high price).
Remove Before Flight Shotgun Chamber Safety Flag
There is one modification which will make your safety flag look terrific! Just add a simple $2 “Remove Before Flight” keychain to your safety flag and here’s how it will look like:
This also serves one more purpose. It is much more difficult to loose chamber safety flag with bright red keychain. This is funny but useful addition to your chamber safety flag! :)
This is updated instruction about Remington 870 safety button replacement. It is more detailed and also has better photos.
When you want to replace the safety button of your Remington 870 you will want to install an oversized safety button. This will allow you to disengage the button more easily, especially if you are wearing gloves or are in a stressful situation where you may lack focus and concentration.
The Remington 870 is an adored pump-action shotgun that is used by hunters, police officers, target shooters, competitive shooters, and military officers. But like any good weapon, it needs to have a suitable safety button that someone can switch on and off in a moment’s notice. You don’t want to have the risk of not being able to push the button fast enough when you’re in a hurry or desperate situation. The factory safety button that comes with the Remington 870 is a perfect example of this. A lot of owners claim this factory safety button is too small for their fingers, which causes them to waste precious time by having to bring the button close to them and push down hard on it. If you’re in a combat situation or need to shoot something quickly, you must be able to keep your hand on the handle while disengaging the safety at the same time. This can be done with your thumb if the safety button on the weapon is big enough.
