On mine, I would not call it loose, but there is a very slight amount of lateral play at the very end of the clip. Definitely nothing significant.
Thanks to all for the info. Mine arrived today. Wow! I was looking for something more pocket-carry friendly than my Fury but with similar features, this is it. Actually a little smaller than I imagined from the specs and photos. Next time I have a couple loose Benjamins I plan on picking up a second one. I never want to be without this gem. I guess Fury is going to live in the glove box now.
I don't know why they didn't make the thing still functional as a weapon mounted light, sell the mount extra, or even cooler would have been to have it magnetically mount although I suppose that could cause unintended side issues like hampering slide speed/operation on a pistol with a steel slight(almost all handguns) or falling off during heavy recoil...still they could have used the regular rail mount and made it easily removable. Seems weird to sell a light designed for weapons as a non-weapon light with no weapon light conversion or capability.
Then you wouldn't have to buy 2. Look at the P2X & P3X Fury. Identical heads, identical switches, glued onto different bodies. If you remove the head the warranty is void. $139 P2X $225 P3X - Common Street Prices. You just paid $86 for 1 CR123 sized piece of aluminum. Not a bad markup.
Or it could be that multimode lights aren't ideal on a firearm.
