I have the 26" Autolock with Hindi Endcap. It helps with drawing the baton and it does prevent the baton from slipping out of your hand. I've only used it in training I haven't used on the job yet. My baton instructor liked it he said it was a good feature to have. :2c: The girls dig it too.... :L:
The Hindi Endcap is a great tool, because it let's you hang onto your baton better. However, there are some drawbacks. Not that this really matters, but it looks like a giant piece of male anatomy when sitting in your duty belt, and this draws alot of jokes, trust me. Personally though, I got rid of mine, because it stuck out too much from the side of the baton, and was constantly poking me in the ribs. Take it for what it's worth.
