Reptilia BlackHole Polymer Magwell – Glock 19/23 Gen 3 & 4 – Black – 100-005
The Reptilia BlackHole™ (100-005) is a minimalist, high-performance magazine well designed to bring the speed of a competition-style flared funnel to your everyday carry (EDC) or duty Glock 19/23. Crafted in the USA from impact-modified reinforced nylon, the BlackHole is engineered to facilitate lightning-fast, intuitive reloads without adding the excessive bulk or snag points associated with metal magwells. In 2026, it remains a favorite for its "seamless" look and feathered weight of only 8 grams, ensuring your sidearm remains balanced and easy to conceal while significantly improving the Target Area for fresh magazine insertion.
What sets the BlackHole apart is its clever cross-generational compatibility. By utilizing a unique modular rear spacer system, it achieves a perfect, gap-free fit on both Gen 3 and Gen 4 Glock frames. It is even compatible with Gen 4 backstraps, a rarity among aftermarket magwells. The integrated front finger rest provides a subtle but effective ledge that drives the hand upward into the trigger guard, enhancing overall recoil control and grip consistency. While it is optimized for standard capacity and extended magazines, please note that it is not compatible with factory Glock 10-round magazines (though it works perfectly with Magpul 10-rounders), making it the definitive choice for unrestricted duty setups.
Includes: (1) Reptilia BlackHole Magwell, (1) Gen 4 Spacer, (1) Custom Alloy Steel Screw, and (1) Hex Wrench.
