ThyrmLow Profile Carry Clip for Flashlight (LPC Clip, fits Many 1" Diameter Lights, Black) for Pocket or MOLLE Retention, Made in USA

This clip works very well on the G2X series Surefire lights. I’ve used them many times and they hold up. Great product.

This clip is great, can't wait to use it at work. It’s a quality product. If you are using the Nitecore MT10C, you will need to use both the metal washer and included o-ring. I am using the IMR18350 battery. The metal washer is essential for its operation. The included washer was only used to stop the clip from spinning freely on the light. Slide the o-ring passed the factory one to where the base of the clip meets the light. The trick to get it from flickering is to tighten the tailcap read good, by hand. Then it will work perfectly. Thanks to reviewer KEN for posting the pic of the MT10C in use with this product, was on the fence bc Thyrm’s compatibility list does not include nitecore.

So, the surefire g2x doesn't come with a pocket clip, or any real way to attach one directly to it. That causes some problems as I bought it with the intention of using it as my duty light. Thankfully, I found this. The installation was super simple as well.The thing itself has been super durable, as I've used my light with it for ~6 months now on an almost daily basis, and it's survived multiple drops, as well as some rigorous trainings.I'd also imagine this is probably the only option, so if you've gotta stick a pocket clip on your light, this is the way to do it

Well... it provides a pocket clip. It is sturdy and it works. But it does so at great expense in both money and size. As a pocket clip it should not need to be this large. It would be much better if it provided a way use a ring so that it would work with Harrys style. The "squirt" method of holding that it supports is not very useful. If you really need a pocket clip, and only a pocket clip, this will work.
