Featuring the patented Automatic Locking System (ALS), it secures your weapon instantly without straps or snaps, allowing for a quick, intuitive draw. Constructed with SafariLaminate thermal molding and suede lining, it offers superior protection for both handgun and optic. The mid-ride belt loop ensures a close, comfortable fit, making it a top choice for tactical professionals seeking reliability and precision. ## Description The 6390RDS holster is specifically designed for firearms with red dot sights mounted to them. This open-top holster features the Automatic Locking System (ALS), an internal locking device that retains the weapon in all directions with no straps or snaps to manipulate. Once the weapon is holstered, it locks into place. The holster is completely operable with the thumb and once the ALS is deactivated a simple straight-up draw is used. Features a mid-ride belt loop that is rides close to the body. Safariland cannot guarantee that RDS holsters will be compatible with non-factory (Glock MOS, M&P CORE, etc.) mounted red dots. Numerous variables including depth of RDS into slide, use of dovetail, placement on slide, etc. Can all affect the fit of the holster. Review: If you know you know! - Top shelf industry standard. Review: Fit Staccato P - This fit my Staccato P with TLR1 and RDS. The fit out of the bag wasn’t perfect but that’s nothing new with Safariland holsters. It took a little loosening up and about 50-75 reps in and out but now it seats like it should and there is no wear on the weapon. ## Features - ALS (Automatic Locking Systems) secures weapon once holstered; simple straight up draw once release is deactivated - For use with red dot optic-equipped weapons - SafariLaminate thermal-molded construction protects handgun and sights - Suede lined to protect handgun's finish - Features a mid-ride belt loop that is rides close to the body ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NYXDW6P | | Best Sellers Rank | #167,030 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #1,757 in Gun Holsters | | Brand | Safariland | | Brand Name | Safariland | | Color | STX Tactical Black | | Customer Reviews | 4.1 out of 5 stars 37 Reviews | | Hand Orientation | Right | | Included Components | Holster, Instructions, Allen wrench | | Item Type Name | Gun Holster | | Item Weight | 13.9 ounces | | Manufacturer | Safariland | | Manufacturer Part Number | 1324671 | | Material | Plastic | | Material Type | Plastic | | Model Number | 6390RDS | | Mounting Type | Belt Mount | | Product Style | Sturdy | | Size | STI STACC P 4.4" X300U | | Style | Sturdy | | UPC | 781602168755 | | Warranty Description | See Manufacturer | ## Product Details - **Brand:** Safariland - **Color:** STX Tactical Black - **Hand Orientation:** Right - **Manufacturer:** Safariland - **Material:** Plastic - **Mounting Type:** Belt Mount - **Size:** STI STACC P 4.4" X300U - **Style:** Sturdy - **UPC:** 781602168755 ## Images ![6390RDS Level One Retention Duty Holster, Red Dot Sight Compatible, STX Tactical Black, Right Hand, Fits: STI STACC P 4.4" Surefire X300U - Image 1](https://m.media-amazon.com/images/I/81o1eUl5haL.jpg) ![6390RDS Level One Retention Duty Holster, Red Dot Sight Compatible, STX Tactical Black, Right Hand, Fits: STI STACC P 4.4" Surefire X300U - Image 2](https://m.media-amazon.com/images/I/81jaS+TTeqL.jpg) ![6390RDS Level One Retention Duty Holster, Red Dot Sight Compatible, STX Tactical Black, Right Hand, Fits: STI STACC P 4.4" Surefire X300U - Image 3](https://m.media-amazon.com/images/I/81d7wLrLunL.jpg) ## Questions & Answers **Q: Does if fit P330 x carry** A: If you mean the 320 xcarry I believe they make one for it. **Q: Will it work with staccato p with sro?** A: Yes it will fit with rmr, sro , Holosun 509t, DPP **Q: Will this work for the staccato p duo with an ice comp, surfire x300u and sro optic?** A: I tried it for a Staccato C2 with an Ice comp.

The fit out of the bag wasn’t perfect but that’s nothing new with Safariland holsters. It took a little loosening up and about 50-75 reps in and out but now it seats like it should and there is no wear on the weapon. ### ⭐ How could safariland put out this garbage? This holster will get you killed *by M***. on March 26, 2024* Not only did my holster show up with obvious wear marks from being used, it was hit or miss whether or not my pistol would seat into the holster. It is the correct holster for my staccato. The ALS lever needs to be buried between the holster edge and hood so you have to use the very tip of your thumb or thumb nail to deactivate it. I wish I could give negative stars for a bad design. --- ## 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.co.za/products/308649009-6390rds-level-one-retention-duty-holster-red-dot-sight-compatible](https://www.desertcart.co.za/products/308649009-6390rds-level-one-retention-duty-holster-red-dot-sight-compatible) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-30*
