Not reliable, purchased this light for our team within 6 months 10 of the lights were 10-7.

I have two of these...one on my G35 all the time, the other in my tac vest for a backup. Very handy when checking interiors on open door alarms. Only problem's I have noted is that sometimes when shooting, the recoil can affect the switch mechanism negatively. This can usually be fixed by removing the back cover plate and reinstalling it. Other than that, an excellent product

I think it deserves a 5 because the light lasts linger and the light is definately stronger.

I like this light so much it is on my house gun too. Nice focused beam and easy to use.

This light is mounted on my Taurus PT92 with a tactical holster, which is my regular duty weapon. I love it. It is super bright and mounts and dismounts easily. I also mount it on my Springfield XD-9, which I also carry on duty. Great light.

I am a K-9 officer and I have this light mounted on my Glock 23. It is a great tool when I am on patrol with the dog lead in one hand and my weapon in the other. Keeps me from fumbling for a flashlight when I am clearing a house or in a tactical situation.

I have one of these lights and have used it for about a year. It's a good light for the money, but there are better lights on the market, if your willing to spend more money. During heavy firing carbon seems to build up under the lense. If you put a small amount of oil on the face of the light it will capture most of the powder and can be wiped of easily.

I got this after losing my flashlight in a foot pursuit with a felony suspect. It is always mounted on my gun and puts out plenty of light. It makes clearing a building a lot easier because you don't have to do a balancing act with your gun and flashlight.

Love this light! If your dept. does't allow weapon lights for patrol officers, work to get the policy changed. The officer-safety aspect of it alone is worth it.

I love this thing, don't know how I lived without it for so long. It is a must have no matter if you work days or nights. If you don't have one you need to get one.

exellant product. there's nothing better than a gun mounted light. shoot with both hands in low light or have a light gun and k9 all at once something k9 officers have been having to choose between for years. the m3 is relatively inexpensive too you can get them for less than $100, i've had mine for about 4 years and never changed a light bulb and only changed batteries once or twice. it's great.

Had this light for about 5 years. No problems. The momentary-off-on swithcing is easily accomplished while maintaining target intimidation. Once you've had a mounted light like this, you'll wonder why you did not get it earlier. The only problem is finding holsters to accomidate a weapon with a mounted light, but light holders are available, too.

bought this and a internal laser could do without the laser but highly recommend the tac light

This is standard issue for our whole department. Love the option of momentary or steady-on operation. I've had the batteries go down while clearing a building and I almost forget how to use my streamlight flashilight in conjunction with my handgun. Great product.

For the night / evening operator this is the best light tool for search / encounter -- no doubt.

i enjoy it works great easy on and off switch and it slides on and off with no problem

I love this light. It is also great as a backup flashlight if your primary light goes bad. I carry while flying too. Great product.

Excellent product for the money. Mine has held up well and the batteries have a long life.

Great light! I prefer it over similar brands on the market.

Great light when working at night it leave's one hand free. Great product.

On more than one occasion the batteries fell out of the light while I was firing the weapon it was attached to.

Friend owns this light he loves it

Good basic light and an excellent target illuminator in a fight.

Excellent item. Great small light/powerful beam. Highly recommended

We have these on our Glock 22, love them.

Great light and doesnt hang up on the holster. Easy on/off an momentary switch. Nice product.

i like the light. i have two of them and keep both close by.

Nothing is better when you are tracking a suspect in a mesquite filed with a pistol in one hand and a dog leash in the other! If only the department would allow the use of lasers with it!

I love this light! Momentary switch is great for tactical entry.

Great light at a reasonable price. I have used this light in conjunction with my glock 22 for a couple of years. Durable and bright enough for tactical purposes. Batteries are cheap and readily available. Quick to deploy and detach. Hard to beat for the price.

Great little light! I use it for so many things. Can't say nothing bad except the batteries are to expensive!

Great for clearing buildings, but if you don't have the proper holster you will forget to use it sometimes. The batteries in mine seem to go down faster than I would like.
