Umarex T4E TP50 Gen2 .50 13J

The German manufacturer Umarex, specifically their T4E department (Training for Engagement) introduces the second generation of their best-selling rubber and pepper projectile pistol called the TP50 Gen2. It’s evident that the company has listened to customer feedback and made welcome changes, and in turn didn’t alter anything that works flawlessly.

The most notable difference, compared to the original version (11J) is the increase in muzzle energy to 13J, making it one of the most powerful short RAM guns in .50 caliber.

The second major change is a new 12g CO2 cartridge quick activation valve. It’s been redesigned to be easily loosened by hand without the need for an Allen wrench. Nevertheless, it still does its job perfectly – in case of a threat, just bump the valve slightly with your palm to pierce the cartridge’s nozzle and the gun is ready to fire. That way, you can carry the pistol indefinitely without the risk of the sealing rings degrading. When activated, an indicator pops up above the grip, signaling that the pistol is under pressure.

Other minor changes include an anti-slip grip texture and fixed sights with light-guiding fibers for easier aiming even in low-light conditions.

The lower Picatinny rail for installing a laser or flashlight and the convenient trigger-integrated safety have remained intact.

You can use all kinds of RAM balls as ammunition, such as rubber, pepper or marking rounds.

Maintenance

Since the gun is powered by CO2 cartridges, the sealing rings can become brittle and crack when exposed to the freezing carbon dioxide over time. This can be prevented by occasional application of silicone oil 1) by a spray bottle, where you simply coat the internal mechanism, 2) by applying a few drops of silicone oil to the nozzle of the inserted cartridge 3) by using an oil cartridge (easiest). It’s also not recommended to leave the activated cartridge in the gun for longer than necessary. If you know you won’t be shooting for a while, release the pressure by loosening the valve.
