If you will ship international, i will pay for the shipping. I need some Surefire o-rings, i used up mine. If okay, i will take the assorted SF o-rings & SF lanyards. Thank you.
The other method... with disclaimer :) is to install the clip up-side-down on the flashlight... then slowly bend inwards or outwards. Handle with utmost care. I used this method to tighten the tension, but haven't tried the opposite.

You can actually put some bending (with care) and see if it has lessen its stiffness. Also, if you prefer a more flexible one, try checking on McBrat Alien clips which are available for sale on this forum. They are so easy on the jeans. Cheers!
