The Modify Trinity Hi-Capa GBB gas pistol is designed not only for CQB or as a backup weapon but also for competitive IPSC shooters. It introduces a unique hop-up adjustment system that allows precise tuning of the BB trajectory without disassembling the gun. The hop-up can be adjusted even during shooting via the slide release, enabling instant trajectory corrections without downtime.
During testing by Modify, magazines from other Hi-Capa brands were successfully used with this pistol, including CO2 and extended magazines. However, each magazine should be tested for compatibility.
The pistol features a lightweight aluminum alloy slide that ensures durability and strength while maintaining a low weight, crucial for fast shooting. The steel trigger mechanism provides long-term durability and reliability, even when using high-pressure gases like Red Gas. Here is a list of parts compatible with Tokyo Marui Hi-Capa.
