No, that's incorrect. There is at least two UK distributors (Edgar Brothers and Modern Trenches), plus one in Germany (Viking Tactics Germany) who carry TYR Tactical; however I don't know whether they actually hold stock. Judging by the shipping times indicated on the Viking Tactics Germany website I would suspect that they order on your behalf. So it's up to you whether you'd rather deal direct with the manufacturer or go through a middleman.
I've previously ordered from TYR directly myself, and have one order in progress at present; their website is easy to use and if they don't have what you want in stock at the time of ordering then they'll let you know the current lead time and then notify you when its shipped. It is worth remembering that they are a relatively small business in comparison to the likes of LBT, Crye etc., so lead times can be lenghty and you may have to contact them for a follow up status check.
Failing that you could hold your breath and wait for one to pop up on the likes of the forums or ebay, but in all honesty it would probably be quicker (even with a lenghty lead time) in going direct to TYR themselves.
