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

Great upgrade from the stock selector on my shotgun. Easy install and works perfect.

Fit perfectly, but it is a little sharp edged for the thumb. Not a deal breaker, but maybe worth considering if you’re going to be shooting extensively.

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.

Super easy to install, works better than the factory switch.

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.

Perfect..nice add on

Fit fine, works fine. I replaced the broken one easily, but I did have to do a tear down because internal parts shifted. I don't know why none of the suppliers I looked at include the little metal slider plate underneath the stock safety. Mine needed to have wear ridges smoothed off to make the slide work smoothly. I did not even try to replace the detent ball as that appeared to be locked into the receiver.I also cannot figure out way Mossback would make the OEM safety so flimsy.

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.
