How to Install Oversized Safety on Remington 870 (Vang, Wilson, Scattergun)
Posted on September 4, 2009
A lot of people want to install an oversized safety on their tactical Remington 870 shotgun. Is it easy to replace a factory safety button on Remington 870? Yes it is. This shotgun is very simple and even a complete newbie can disassemble, reassamble and install upgrades on it. That is what we love Remington 870 for.
Warning: Make sure that gun is unloaded and safety is engaged.
1. First of all you need to disassemble your shotgun and take out the Trigger Plate Assembly (Trigger Group):

2. Place a finger over the safety detent spring hole and push the safety detent reataining pin out using 1/16 inch
pin push or something that will fit:

The detent spring is under pressure and it may jump out of the hole if you will not place your finger over the detent channel.

3. Carefully allow safety detent spring and ball to drop from safety detent channel.
4. Remove the old safety button and install new safety from the right side.
Attention: Vang and Scattergun large safeties are designed for use in right hand shotguns only.
5. Reinstall the safety detent ball and spring, depress the safety detent spring into safety detent channel and replace the retaining pin with the pointed end first.

I went with the Wilson/SGT after reading a couple of complaints about the Vang comp sticking out too far. Picked it up at Tanks Rifle Supply for about $15.00 shipped.
