Umarex Trevox Gas Piston Air Pistol

  • TNT gas piston
  • SilencAir - noise dampener
  • Reinforced SilencAir is the cocking handle
  • Fiber optic sights
  • 18.25" overall length
  • 3.15lbs

With its Turbo Nitrogen Technology (T.N.T.) gas piston, the Umarex Trevox is a real tack driver! Capable of shooting lead pellets at 540 fps, and alloy pellets at speeds up to 600 fps, the hard-hitting Trevox is up to the task for target shooting and plinking.

Simply cock the grooved barrel and you’re ready to shoot! Take aim with the included fiber-optic sights, or mount your own optics to the 11mm Dovetail rail. The Trevox features a 3 chamber SilencAir baffle system to keep your shots quiet.

If you want power in a pistol platform, make the Trevox your go-to airgun.

Things I liked: -It’s very accurate. My guess is that it should be close to the accuracy of my PowerLine 717. -Powerful. About twice the power of the typical air pistol. I measure it to be about 4.4 FPE. -Cocking and loading is easy and quick. Faster than a single pump with bolt. -Piston recoil is light. -It looks to be ruggedly made. -Trigger pull is not too heavy. -Decent adjustable sight. -It’s the quietest air pistol I have. Equal to my PowerLine 717, but deeper. -Nice dovetail for my reflex sight. -The weight is not that heavy. It’s noticeably lighter than my PowerLine 717. -Exceptionally consistent velocity. With 3 different brand pellets the max spread I measured with 5 shots was 9, 10, and 11.

Things I would have changed: -Trigger pull has a lot of creep. No doubt it affects my accuracy. Its the biggest criticize I have on this, but then so many airguns dont have very good triggers compared to firearms. At least it’s smooth. -Cocking makes a small creaking noise. -Adjustable sight elevation has no detent (clicks) and may go out of adjustment over time. -Windage has a detent, but I don’t like that it’s a knob.

What others should know: The Trevox is a potent accurate pistol. After breaking in with a couple hundred shots the velocity with H&N FTTs measured 479 FPS, which is about 4.4 FPE. For accuracy it favors the H&N FTTs. I get better than a 0.5 inch group at 6 yards (limitation of my basement). Crosman Premier WCs tend to shoot off to the right by an inch in a 1 inch group. In summary, it’s my current favorite air pistol. I’ve already recommended it to a friend looking for something with power and accuracy. It has less flaws than I saw related to other brands of this class or type.

Things I liked: Its a pistol. Very easy to cock. Too silent

Things I would have changed: Size, i need gorilla hands to have proper grip. Inaccurate no matter ammo. Silencer is a huge PITA, make it removable?

What others should know: Its an easy backyard shooter... within 10-15 feet. The kids 6-9 here love it because its easy to cock/load but its "way toooooo heavy". The silencer is nice but a huge problem since you can't use certain ammo with it on and cleaning is harder :(

  • JOHN from USA asked:

    What is this child proof trigger that is talked of? Is it just the trigger pull weight?

    • Tyler from USA:

      People are just referring to the pull weight required to break the sear.

  • Fritz from USA asked:

    Has anyone put a Red Dot sight on this pistol? If so what worked? Fritz

    • buck from USA:

      It works better than the built-in sites. The gun itself so far, I haven't found the pellets that work well. I mean the variation of pellet quality within the batch effect the accuracy. Still looking for the right pellet. It has shoot straight many times you just don't know when. Alloy pellets were crazy flyers don't see that as an option with this gun. Still like it, the gun will never be a nail driver, ever!

  • Deter from USA asked:

    I have weak arms lol. How hard is it to cock this gun? Similar to the 6-7th pump from a c1377 pistol? Or any info on "lbs"? Im really debating this purchase. I wanted a brake barrel NP pistol since i got this crossman fire NP rifle.

    • Deter from USA:

      Answer my own question. This is very easy to cock. Similar to the 3rd pump of a 1377
