Came with all the parts I needed and installation guide. Fit perfectly! ### ⭐⭐⭐⭐⭐ Fit, finish and function great *by D***W on September 19, 2023* 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 ### ⭐⭐⭐⭐⭐ WORKS LIKE ORIGINAL/HIGH VISABILITY *by H***E on May 22, 2024* 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. ## Frequently Bought Together - NDZ Performance Safety Replacement Kit for Mossberg 500 590 88 835 940 12/20 Aluminum - Ball & Steel Plate Complete Kit - Choose Color & Kit - Magpul Industries MOE M-LOK fits Mossberg 590/590A1 Black Forend --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/430311497-ndz-performance-safety-replacement-kit-for-mossberg-500-590-88](https://www.desertcart.sk/products/430311497-ndz-performance-safety-replacement-kit-for-mossberg-500-590-88) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-06-18*
