870 left hand safety

[Virginian]

Buy a regular right hand safety button and swap them. That's the only difference. And no, you cannot reverse the one that's in it. Mechanism is offset.

If you haven't, download an owners manual and look at the parts diagram. Remove the trigger group. Take the safety off, put your thumb on the hammer, pull the trigger and gently release the hammer tension. Then you have to drive out the Safety Mechanism Retaining Pin. Do not let the spring and detent ball fly out and get lost. Dump the ball and spring out of the hole, remove old safety, install new safety, put ball and spring back in hole, reinsert retaining pin.
