for Mossberg 500 590 835 930 935 Shockwave Accessories Enhanced Slide Safety

The original safety knob on the Mossberg M590A1 seems designed to separate your thumbnail, from the nail bed every. single. time. you engage it - even wearing gloves! My only regret about this upgrade is that I waited so long to do it. WATCH A HOW-TO VIDEO FIRST! After watching a video that let me see how to install the new knob without losing the tiny ball-bearing in the works, I was able to easily swap this part out in just a few minutes. I would never go back to the OEM safety knob after using this one - and I really like the red color. The parts are well made, the anodizing seems high quality, and I don't doubt that it will last a lifetime, just like the rest of a Mossberg shotgun.

This fit my western field and my new haven shotguns well had to replace broken originals that were plastic

Nice finish, however, the detents are just deep dimples, to get the safety to slide smoothly, it is necessary to make a short shallow groove leading into the detent. If you don't make the grooves, it will be difficult to move the slide between SAFE and FIRE. Before installing, be sure the shotgun slide is cocked, open, and the safety is ON or you will spend a bit of time recovering the internal safety latch when you remove the screw from the safety slide.

It works.. but missing the spirng

Buy it now! The stock safety is a bitch to use, that's why you are here. I should of done this years ago!!!!!! Installation on the 500- read it all first.Remember, unloaded check, check again, safety on, open action all the way, safety is on, use a wire tie or a few bread twist ties and hold tension back on the trigger, this will keep the inner mechanism from falling in side when you take screw off( if it does fall in- no big deal just more time - a breakdown and cleaning now that your going in-) keep gun up right, a vise or a few gallon water jugs sandwich it.When you take screw off keep down pressure because tiny spring and ball bearing wants to fly off. Set up something under to catch all if you are clumsy.You will use the backing plate under the switch again for the new switch.Dab a little gun greese under and side of all.Some loctite or similar recommend put on screw.Easy as you apply a little pressure to all and thread screw in.Done? Yup fantastic told ya!

Definitely an upgrade to your Mossberg shotgun. The stock safeties are notorious for sticking and not being adjustable due to a one-way safety screw. These have a nice adjustable Allen bolt so you can tighten or loosen your safety over time which is nice. The large thumb-tab also makes it much easier to toggle, especially with gloves on. They're also aluminum instead of plastic, which should last longer. I bought a Mossberg so I can still use it at 99, and I'm not sure why the new ones have so many plastic components compared to my dad's Vietnam era one.My one note is installation is not the easiest. During installation, my safety fell into the receiver and I ended up having to disassemble the trigger mechanism to get it back. Some forums suggested laying the shotgun on its side during installation to prevent this from happening, but I'm not sure how well this would work. Also, to remove the original safety screw I found it works well to put a piece of duct tape over it and then unscrew it as a normal screw through the tape.

Perfect..nice add on

The machining is a little aggressive, it looks great, and works well. but doesn't feel very good on your thumb over time if your using it a lot. after a a day at the range my thumb was kinda raw and sore. I put the factory back on.
