I bought this last year and have used it 3 times.  It's a pretty cool holster that retains based on the light attached to the pistol rather than the pistol itself - making it really handy if you like to swap pistols reguarlly!  It will work on Surefire X300 and X300 U-A models - taking pretty much any pistol that you attach it to (full details on Blackhawk's website)

I'm including the original belt and paddle attachments, along with a Blackhawk Molle plate.  I'm also including some longer screws which mean you can mount it to the molle plate or a Blackhawk leg platform.

These retails new for £70, I'm asking £35 including postage and PayPal fees (Goods & Services)

Any questions just let me know.

***It’s been pointed out to me this may be a copy as Surefire is mispelt on the packaging.  I bought this from a Genuine UK Blackhawk retailer (can provide receipt), the quality is what I would expect from them and it certainly works fine.  I can’t see any copies of the Omnivore for sale online so I am a bit unsure!  May just be a spelling mistake from the factory.  Dropping the price by £5 due to the uncertainty***
