I have been carrying a Lagriffe strapped to my vest while on duty for a long time. Always in the original sheath it came with. It is starting to loosen up a bit and I want to know what THE best after market sheath is. It has to be VERY secure and stay that way a long time. I don't need that edge bouncing around freely between my shirt and vest. Let me know what your experiences have been if any. I already have a few extras from the factory. Just looking for something different. Thanks for your opinions. Please only give me the ones you actually have experience using. It needs to work!!!
