The VT GMR-001 magazine release is an excellent upgrade for those with average- to small-sized hands, allowing for quick and efficient magazine changes without shifting your firing grip. Designed for easy installation, the GMR-001 is crafted from the same durable polymer as the Glock factory part, ensuring both reliability and toughness. Its extended release is perfectly sized not too short, not too long so you can rest assured that the magazine won't accidentally release when the pistol is laid on a hard surface. This release is ideal for use with back strap-mounted lasers, making it a great addition to your setup. Compatible with Glock Gen 1, 2 and 3 pistols, including models G17, 19, 22, 23, 24, 26, 27, 28, 31, 32, 33, 34, 35 and 37. Please note, it is not compatible with Gen 4 pistols.
