Which metal Mossberg 500 safety to buy?

I have this setup (promag safety with beat sight) on my 500 Mariner. No, the safety does not interfere with sight picture when looking directly down the barrel.

Hi,
I put the Brownell's or Pro Mag on my LH 590A1.
There is no way for your thumb to "skid" off the top with it!

Picked up a Triceratops Customs. Mainly because it included the screw and Allen wrench (though I have a complete set of them).

Finally! A company that includes the new screw. Why can't they all do that?

Several do or you can reuse the one way screw.

Used the masking tape trick and forgot about the detention ball. Fortunately I was able to find it. I put the hump to the rear as I felt I could get a better grip on it to put the 500 into safe.

I bought one of the NDZ safeties off eBay. it looks like the one in the top picture in the original post, except I bought it anodized in red so it can be seen at a distance, for when perhaps a cousin or Nephew might be holding that shotgun. I think I paid ~$9 shipped It came with an Allen head screw and the correct Allen Key for it

I like that one too. Ordered a 'kit' for my Daughter's Mossy and the follower for mine...since I already had replaced the safety on it.

That is what I put on mine as well.
