NDZ Performance Safety Replacement Kit for Mossberg 500 590 88 835 940 12/20 Aluminum - Ball & Steel Plate Complete Kit - Choose Color & Kit

Works good and great quality! Came with all the parts I needed and installation guide. Fit perfectly!

I have ordered NDZ products in the past they are of high quality I have never had any issues with a ease of installation they make things very simple to put in most items are very simple to put in but if there's any question about it it's pretty much step by step I use this to replace the safety on one of my firearms in our shop it was easier to grip onto with your finger then the stock one was making it much easier to use in the field as long as NDZ stays in business I will always purchase products from them

This fits perfectly on my Mossberg Shockwave. I like the bright color as it easy to see where the button is, even when using my firearm with a pistol grip. Some people complain that having the safety on top is hard to reach. I must have big hands as I find it not to be a problem, and can easily see where the safety is without rolling the firearm on its side, or feeling around for the button.

Perfect replacement. Multiple videos that adequately describes the process to install the new, much improved safety lever are available. Printed instructions were through but not overwhelming.

Works great but since its metal can be rough on thumb

Super easy and quick installation if you follow their recommended method shown on their youtube channel. Took me maybe 5 minutes at most. I put this on my Mossberg 500 which already had a plate and ball bearing. There is a little bit of give between the safety and receiver, but other than that it’s very tactile, feels like a solidly built safety, and makes the safety much easier to control.

Pretty well made piece I have the all black one Had to file off the corners on top as they are too sharp for my liking, used black magic marker to cover the bare aluminum caused by the file. TIP" Order and replace the ball detente spring if servicing an older firearm. Use a dab of red grease to hold the detente ball in palace while fitting he steel plate and safety switch otherwise a bottle of headache pills will be required. Mine is a tad bit stiff but my firearm is dated 1980 so no big deal.

5 minutes some lube, and a little blue lock tight.
