for Mossberg 500 590 835 930 935 Shockwave Enhanced Tactical Slide Safety by NDZ Red

love this upgrade. makes the safety very smooth and easy to operate. I will admit that due to issues with the Mossberg safety I would put it on "fire" and leave it there at the range. now I actuate it every time. Great, I would say a MUST.

Nice safety. Well made. The directions could be better. You need to retain the mounting plate from your old safety as the new one does not include it. There are some good videos on YouTube that show installation process as well as provide some instructions on what not to do.

Easy install; just make sure you don't lose the ball and spring in the process. Much more positive safety that's easy to activate. I like it.

This is a great upgrade. The stock safety is functional and works, but I use my shotgun for defense and wanted something a little more positive under stress. This is exactly what I needed. It’s reversible, so you can put the extension close to the rear, or to the front. It’s very easy to install, the Mossberg factory screw isn’t as bad to remove as people make it out to be if you take your time and be careful. But thankfully this comes with a proper screw. Just be careful with the detent ball, and reuse the factory spacer.This is a very well made product and for me was a cheap upgrade that made a big difference for me.

Easy to maneuver and not too difficult to instal just be aware of the ballbearing

My safety switch gave up the ghost after 11 years and roughly 6000 rounds. This solid piece of aluminum should last the rest of my guns life. Instructions where ok, but if you can clean your Mossy, you can install this safety. Go slow, watch for the little ball, and use a little blue loctite. Took me less than 10 min, including giving the gun a quick cleaning.

Like the fact that the safety is now metal. Be sure to READ DIRECTIONS FIRST. Orig safety has a detent ball and spring, disassemble and assembly over tray and have magnet handy to catch TINY detent ball when, not if, it pops loose..

Looks much better than the original safety and has a nicer feel! Would recommend
