Umarex Defense Gun Generation Correspondences
This page aims to list the different versions of Umarex defense guns, to make it easy to find your way between models and their generations. The market for defense launchers evolves quickly, and manufacturers regularly update their ranges: new generations, commercial name changes, new references. It then becomes difficult to know which accessory fits which model.
Some references can be confusing, particularly when the commercial name changes from one generation to the next. This is the case, for example, with the HDR 50, whose initial version corresponds to the Gen 1, while the Gen 2 is now sold under a different name. Without a clear reference, it's easy to end up ordering an accessory intended for a different version.
This page therefore serves as a clear reference between the old and new versions, indicating the correspondences between names, to avoid any error or misunderstanding when choosing your gun or your accessories. Here you'll find the main models in the range and their generation 2 equivalent.
T4E TPX 50 Gen2 (New for 2026)

T4E Impax P68 (New for 2026)

HDR50 > TR50L Gen2


HDR68 > TR68 Gen 2

HDP50 > TP50 Gen 2


HDS68 > TS68 Gen 2

HDC68 > TC68 Gen 2

HDB68 - TB68 Gen 2

HDX68 > TX68 Gen 2

In summary, the new Umarex naming replaces the "HD" prefix with a name starting with "T" on generation 2: the HDR becomes TR, the HDP becomes TP, the HDS becomes TS, the HDC becomes TC, the HDB becomes TB and the HDX becomes TX. This logic lets you quickly identify the recent equivalent of an older model, or conversely find the older reference of a latest-generation gun. This is particularly useful when choosing an accessory, since compatibility depends on the exact model and its generation.
