You might wanna say if you are interested in the Joker or Standard UX1K version as the very first UX1K HD45 that were released are Joker lights with a different beam distribution. This was the time when Don discivered the Joker issue.
To Joker or not to Joker is a good question that I don't know the answer to. I have purchased a HD45 from the Shoppe recently and I was very happy with the performance of the light. I don't know if it is a Joker or not.
I am open to either I guess with my preference leaning toward the one with the most throw.
