I had only seen the Elzetta clip on an Alpha and thought "man that thing really looks awkward".
Then I looked into the clip itself for use on my Bones.
This I can like.
Combine with their nearly wire thin, super strong lanyard ring one gets a grip ring, a rotatable lanyard ring if you like those finger rings. But on the typical (non Dark Sucks clip) the hole for finger ring is protruding from the opposite side as the clip. That creates a bur to your leg when using the clip to hold the light inside your trouser pocket. Being rotatable that is not an issue.
The clip is awesome. It comes with a rubber ring where you slide the clip/ring over the light, then the rubber ring and pull the clip onto the rubber ring. It acts like Chinese handcuffs once things are in position. The harder you pull the tighter the fit.
Instructions are for the Alpha.
Disregard the 2nd sentence in step 2 and reverse the gasket for some lights including the Bones.
Aids overhand, cigar and underhand grip when only wanting momentary on/off as well as general use and.....
Fits other 6 volt cop lights well.
The Laser Products 6P with a Malkoff clicky, lanyard attached and a Malkoff M61W now has an antiroll that doubles as a pocket clip/grip ring.
Tried on a 6P, a G2x Pro, a Pelican 2320, MD2, a Streamlight Strion and a Streamlight Polytac it worked great.
On the Strion a couple of wraps of teflon tape was needed to gain the max grip...
At $15 each it's well worth the coin.
