Side Impact Reinforcement TabsTM (SIRTTM)

Hard side impacts are the achilles heel of all other existing magwells which attach to the mainspring housing. Hard side impacts to the magwell can cause the funnel to twist. They can twist to the point where the magwell becomes so out of alignment, that the magazine becomes stuck in the gun, and/or the new magazine cannot be inserted. This is real, it happens, and can spell disaster if the pistol is being deployed in a critical use situation.

The Chen Magwell Gen2 adds two Side Impact Reinforcement Tabs, which effectively eliminate this weakness. The tabs snugly engage against the sides of the pistol frame, and provide a tremendous amount of lateral support to the magwell. Additionally, the pistol’s grips are relieved and further add support the the tabs, and thereby magwell, from the outside. The Chen Magwell Gen2 will simply not twist from any reasonable (and almost any UNreasonable) side impact, to include banging into walls, doors, vehicles and being dropped from heights that would cause serious bodily injury.
