The German company Umarex, more specifically their division T4E (Training for Engagement), presents the second generation of the best-selling revolver for rubber and pepper projectiles called TR50 Gen2. It is clear that the manufacturer has listened to customer feedback and made welcome changes, while not unnecessarily altering anything that works flawlessly.
The most significant difference compared to the original version is the new valve for activating the 12 g CO2 cartridge. It has been modified so that it can be easily loosened by hand without the need for an Allen key. It still performs its function perfectly – in case of danger, you only need to lightly strike it with your palm, which pierces the neck of the cartridge and the gun is then ready to fire. A revolver prepared in this way can be carried for an unlimited time without the risk of degrading the sealing rings. After activation, a so‑called pressure indicator extends above the grip, indicating that the revolver is under pressure.
Other minor changes include a non-slip grip texture, sights with fiber-optic light-guiding rods to make aiming easier even in low light conditions, an upper Picatinny rail extended by one segment for easier mounting of a larger red dot sight, and a deepened area around the magazine safety.
The lower Picatinny rail for installing a laser or flashlight and the convenient trigger-integrated safety remain unchanged.
As ammunition you can use all types of RAM balls, such as rubber, pepper, or marking projectiles. Thanks to the rotary magazine, the revolver is also compatible with non-spherical projectiles.

Maintenance
Since the gun is powered by CO2 cartridges, the rubber seals may, over time, become brittle and crack due to the freezing carbon dioxide. You can prevent this by occasionally applying silicone oil 1) in spray form, simply spraying the internal mechanism, 2) applying a few drops of silicone oil to the neck of the inserted cartridge, 3) using an oil cartridge (the easiest method). At the same time, we do not recommend leaving an activated cartridge in the gun longer than necessary. If you know you will not be shooting for some time, release the pressure by loosening the valve.
