I know Willie Anderson shoots a release in his XT Unsingle. I don't know who did it but he makes it work well as he made the All American Team again this year in Sr. Vet. I saw him use it Sunday @ Mt. Blanchard Gun Club.
I have the XT Unsingle combo with a double release by Jerrie White. They work flawlessly as all my Browning releases have--no problems with them at all.
I enjoy the release trigger due to my flinching but still use a pull for skeet and sporting clays........flinch once in a bit but don't shoot enough of them to worry about it.
steamer- I'm having my XT combo converted to double releases as we speak. Can't wait to get it back into my sweaty little hands! I'm having Thurman Goble out of Kenton, Oh. do it. He'll do it for $180 per. He'll stand behind his work too. A real nice gentleman. If you need it, PM me for his phone #.
