I have multiple other TrustFire flashlights for home, work and EDC. When I saw this weapon mounted light, I knew I was going to get a high quality product. TrustFire didn't let me down. I currently have an Olight pl-mini Valkyrie 400 lumen weapon light mounted on my Glock 19 that I compared this TrustFire GM21 to. First, I'd like to list some of the similar features of both lights. They both mount with a quick release lever and both come with a Glock and 1913 picatinny rail adapters. Both have ambidextrous switches and built in batteries with indicator lights. They both seem to be equal in size and weight. Time for the differences between the two. THE PRICE!!! I paid close to $100 for the olight and only got 400 lumens. The GM21 is about $40 less and offers 510 lumens!!! When compared side by side, the GM21 has a brighter, whiter and more focused hot spot than the olight. The light spill is less than the olight and the beam reaches out farther as well. One main feature I like on the GM21 is the micro USB charging port. You can charge this light pretty much anywhere without carrying around a proprietary magnetic USB charging cable like the one olights come with. One more thing I have to mention is the ease of operation. The olight requires the user to push down on the switch while the GM21 is a press in style which feels more natural. The GM21 switch has a nice tactile feel when pressed and features a steady on and momentary function. I'm really glad that TrustFire left out all the bells and whistles that other lights come with like strobe function and selectable brightness. I really like how simple the light is and how easy it is to operate. I took it out to the range and fired about 300 rounds of 9mm. The light stayed on for about 40 minutes before the red led lit up indicating a low battery. Not once did the light flicker or shut off after continuous rounds. I also performed a 4 foot drop test into solid concrete and the light stayed on without any issues. Charging was fast with a 3.4 amp USB charger, although I don't really recommend using a high amp charger all the time as it will reduce the battery life. Over all, I recommend the GM21 for anyone who wants a weapon mounted light on a budget. I will keep this light on my home defense/EDC pistol. Review: Look no further this is the light you need - This gun light is perfect. The product came in great time un-damaged. The Packaging was intact and all parts where in there. The light itself I love. It is not to bright where it is blinding you when you point it at a wall and can not see your target, but it is bright enough to light up the hallway and the rooms around it. The light came with a charge and worked immediately. There is a LED charging indicator that is on it so when it is charging you can see if it is charged or not (nice feature). It is able to charge when still on the weapon. The tails when’re you click the buttons to turn on are in perfect placement. If you hold it is momentary and it you click it then it is on. I love that there is not a strobe mode on it. If I could make two small suggestions it would be 1 if there could be a lock out mode, so during transportation you are not worrying about it turning on. The 2nd if the bar that clicks into the picatinny rail was adjustable back and fourth and could work on more guns. Other then that this light is perfect and exactly what I was looking for. ## Features - πŸ”” Bright and Compact: Designed with HI LED, delivers a beam up to 510 lumens with 75 meters of throw, runs 45 minutes. compact and lightweight body makes it an excellent choice for concealed carry, its slim but durable hard anodized aluminum body is only 1.24inches long and 1.94 ounces weight.so it won't weigh down your handgun. - πŸ”” Micro-USB Charging and Battery Indicator: incorporates USB charging system for maximum convenience, can be powered by all common USB power sources,the light on the side features a low battery indicator which will glow red until the weaponlight is charged fully then the indicator will turn green. - πŸ”” Quick Mount/ Detach System: allows users to install and remove the weaponlight quickly.Included are two mount adapters (1913 and GL) to attach the weaponlight to any Picatinny or Gl style rail via its swing arm mount. - πŸ”” Fully Compatibility: compatiable with both Gl and Picatinny style rail mounts, including Gl 17/19/20/22/23/25/32, M*P M2.0 3.6/4.0/4.25IN, M&P M2.0 full size versions, SIG SAUER P226/P229/P320V, HK VP9 SK, CZ P10C, RUGER SR9 - πŸ”” Package Included: TrustFire GM21 Pistol Light, 1913 Rail Mount, T6/T8 Socket Head Wrench, Micro USB Charging Cable, User Manual ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QG1D814 | | Additional Features | Durable,Lightweight,Pistol | | Batteries are Included | Yes | | Battery Description | Built-in rechargeable lithium-polymer battery | | Battery Type | Lithium Polymer | | Best Sellers Rank | #1,338,870 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #2,485 in Tactical Flashlights | | Brand Name | TrustFire | | Color | Medium black | | Customer Reviews | 4.4 4.4 out of 5 stars (114) | | Included Components | Cable, User Manual | | Item Weight | 1.94 Ounces | | Light Path Distance | 75 Meters | | Light Source Type | LED | | Mounting Type | Rail Mount | | Number of Light Sources | 1 | | Power Source | Battery Powered | | Recommended Uses For Product | Weapon light for low-light or dark conditions, concealed carry, or tactical operations | | Runtime | 45 minutes | | Specification Met | Yes | | Style Name | Durable,Rechargeable | | UPC | 682141831554 | | Unit Count | 1.0 Count | | Warranty Type | Extended Warranty | | Water Resistance Level | Water Resistant | | White Brightness | 510 Lumens | ## Product Details - **Color:** Medium black - **Light Source Type:** LED - **Power Source:** Battery Powered - **Special Feature:** Durable,Lightweight,Pistol - **White Brightness:** 510 Lumens ## Images ![TrustFire GM21 Pistol Light 510 Lumens Gl ock Weapon Rail Mounted Flashlight Bright Gun-Light USB Rechargeable Quick Release Compact - Image 1](https://m.media-amazon.com/images/I/511dG26Ge3L.jpg) ![TrustFire GM21 Pistol Light 510 Lumens Gl ock Weapon Rail Mounted Flashlight Bright Gun-Light USB Rechargeable Quick Release Compact - Image 2](https://m.media-amazon.com/images/I/61MqHTxeHnL.jpg) ![TrustFire GM21 Pistol Light 510 Lumens Gl ock Weapon Rail Mounted Flashlight Bright Gun-Light USB Rechargeable Quick Release Compact - Image 3](https://m.media-amazon.com/images/I/51KVfRoRSjL.jpg) ![TrustFire GM21 Pistol Light 510 Lumens Gl ock Weapon Rail Mounted Flashlight Bright Gun-Light USB Rechargeable Quick Release Compact - Image 4](https://m.media-amazon.com/images/I/61JbqsN3neL.jpg) ![TrustFire GM21 Pistol Light 510 Lumens Gl ock Weapon Rail Mounted Flashlight Bright Gun-Light USB Rechargeable Quick Release Compact - Image 5](https://m.media-amazon.com/images/I/61Ti4sSbpkL.jpg) ## Questions & Answers **Q: Will it stand up to being mounted on a shotgun?** A: I wouldn’t mount it to a shotgun **Q: Will it fit a glock 35 gen 3?** A: This fit my glock 17, 34, and 21. **Q: Will this work with the smith & wesson sw9ve rail?** A: Smith & Wesson: works for Handguns with accessory rails like M&P and SD series but not SW series,thanks. **Q: Will this fit my xd 40?** A: Yes, this light can fit your XD40,thanks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A lot of light for the money! *by J***R on May 21, 2019* This light is amazing!

A good thing imo. The light has one setting -blinding and the battery lasts for about 2 hours. Not a huge deal to me, but its something you have to keep in mind. Light switches are Olight, so good there and the charging port is standard Andoid instead of the proprietary magnetic charger. Both pretty good for me since i have a galaxy and carry a charger with cord. Overall, it's a pretty poor light for combat, but a good light for self defense. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/131069590-trustfire-gm21-pistol-light-510-lumens-gl-ock-weapon-rail](https://www.desertcart.hr/products/131069590-trustfire-gm21-pistol-light-510-lumens-gl-ock-weapon-rail) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-16*
