It was very easy to do as the sight kit contains the installation tools and the locktight! The sight is great for "NO" light conditions as you can find the gun in the dark (glowing dots) and aim effectively as well. A quality sight for the money!! Review: Pretty good - Kit did not include 1.3mm allen wrench for removal of stock front sight. Incomplete kit aside, the sight is very clear in the dark and easy to align. ## Features - Larger front sight improves the speed of front sight acquisition - White dot reflects light for best visibility in low light - Express rear prevents obstruction of front sight when moving ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00O8FY572 | | Brand | XS Sight Systems | | Brand Name | XS Sight Systems | | Customer Reviews | 4.7 out of 5 stars 16 Reviews | | Global Trade Identification Number | 00647533042642 | | Included Components | Sight | | Item Display Dimensions | 8.25 x 5 x 1 inches | | Item Display Weight | 1 Pounds | | Item Type Name | XS Sight Systems, DXT Big Dot, Walther 99, PPQ, S&W 99 | | Item Weight | 3.2 ounces | | Magnification Minimum | 1 x | | Manufacturer | XS Sight Systems | | Manufacturer Part Number | WT-0004A-5 | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Name | WT-0004A-5 | | Model Number | WT-0004A-5 | | Mounting Type | Trigger Guard | | Night vision | Yes | | Sport | Hunting | | Sport Type | Hunting | | UPC | 647533042642 | ## Product Details - **Brand:** XS Sight Systems - **Sport:** Hunting - **Item Weight:** 3.2 ounces - **Material:** Alloy Steel - **Magnification Minimum:** 1 x - **Mounting Type:** Trigger Guard - **Night vision:** Yes - **Model Name:** WT-0004A-5 - **Manufacturer:** XS Sight Systems - **UPC:** 647533042642 ## Images ![WT-0004A-5 Dxt Big Dot, Walther 99, PPQ, S&W 99 - Image 1](https://m.media-amazon.com/images/I/71zlZ3Mh0iL.jpg) ![WT-0004A-5 Dxt Big Dot, Walther 99, PPQ, S&W 99 - Image 2](https://m.media-amazon.com/images/I/41pbCyXLacL.jpg) ![WT-0004A-5 Dxt Big Dot, Walther 99, PPQ, S&W 99 - Image 3](https://m.media-amazon.com/images/I/3132g9p8gGL.jpg) ![WT-0004A-5 Dxt Big Dot, Walther 99, PPQ, S&W 99 - Image 4](https://m.media-amazon.com/images/I/41KYzSiHuWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Happy with My XS Big Dot Sight *by J***R on October 11, 2016* I installed the Big Dot sight on my Walther PPQ 40 S&W. It was very easy to do as the sight kit contains the installation tools and the locktight! The sight is great for "NO" light conditions as you can find the gun in the dark (glowing dots) and aim effectively as well. A quality sight for the money!! ### ⭐⭐⭐⭐ Pretty good *by C***S on March 22, 2017* Kit did not include 1.3mm allen wrench for removal of stock front sight. Incomplete kit aside, the sight is very clear in the dark and easy to align. ### ⭐⭐⭐ Just OK *by A***M on August 27, 2017* I watch a few YouTube reviews and thought these would be great, but in actual use they were just OK. I can't say I shoot any better with these sights verses standard 3 dot sights. There were very easy installs on Walther PPQ M2 9mm --- ## 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.fr/products/101287971-wt-0004a-5-dxt-big-dot-walther-99-ppq-s](https://www.desertcart.fr/products/101287971-wt-0004a-5-dxt-big-dot-walther-99-ppq-s) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-05-22*
