Any tips on keeping Streamlight head from loosening?

Anyone have tips/suggestions on keeping Streamlight head from loosening?
I'm running a streamlight tlr7 on an HK VP9, and the lens head likes to back off and loosen when I'm shooting. The result is the light not coming on when I'd like it too, because the battery isn't held tightly anymore.

Rechargeable? Then a dab of blue medium strength thread locker. Or wrap teflon tape around the threads - unless the threads make contact.

Not rechargeable. It runs on the usual CR123A batteries.
I was leaning towards Teflon tape or thread locker. So sounds like I was on the right train of thought.

What po18guy said. Be sure to use the blue Loctite and not the red.

Buy surefire….. hahaha

Are you missing the o-ring on the bezel side? If so, replace it (Streamlight will send you one). if not, it may be worn and need replacement.

Do not loctite it or you'll have a hell of a time getting the bezel off to replace the battery. Those things don't have much purchase area for unscrewing as it is.

You cant loctite the threads or use tape because thats how you turn the thing on.

Or double up on the o-ring to give it more resistance.

Haha. I knew someone was going to say this

Oring is a little bit loose. Might just need replaced or doubled up.

Buy an olight. Never had a problem with them

O ring sounds like it's need of replacement.

 

[Member 34319]

Another thought, it might be a knock off? Especially if there is no O ring.

I don't have a weapon mounted light but I have a stream light I keep in my pocket all the time. It's been dropped from several different heights and is almost always asked for when co-workers or contractors start looking in dark places.

I ended up asking for it as a gift at one point when I couldn't think of something reasonable. I have used it 100x more then I expected I would.

It's been sick a good light I got a different model for my wife and it been in her purse ever since.

Same. I run surefire X300s on my pistols but my handhelds are all streamlights. Cheap and they are rock solid. I've ran them through the washer, dropped them, thrown them (anger management) etc. and they keep on working.

With that being said I have broke two TLR-1 weapon lights and the tape switch on one of the Pro Tac 1000 lumen weapon lights. Their customer service is great though and they will send you replacement parts no questions asked.

Why not just use the switches on the back of the light?....

To clarify, you turn the TLR7s on and off with the lens housing. The switches in the back are only to activate the light during use.

Definitely not a knockoff. It's about 3 years old, so the worn O-ring suggestion seems likely. When I checked the o-ring just now, it was fairly loose.

I haven't tried a streamlight pistol light yet , but have definitely bought a couple dozen handheld versions. Great lights, but I almost see them as disposable. I figure 5 years is acceptable value for the price.

10 years and still kicking on this little guy. The sad thing is I've lost Benchmade knives/spyderco knives etc but I have yet to loose this thing. I just wish Streamlight made clips that didn't pop off the light body so easily. That's my one complaint.
