D-Series Ringed AL Black Hard-Coat 7075-T6 Aluminum Handle

available as an UPGRADE KIT

This can be used to replace a D-Series handle, notably converting a Red Polymer handle on an SS-Poly Hybrid to have a stronger Handle.

Alternatively it can be used to convert a Fully Stainless Thrower Edition to have a lightweight Black anodized Handle, noting it is a reduced strength, but still strong enough for EDC duty carry.

Compatible with:

UPK-D1, D2, and D4
