it is from a Mono Gun and yes, should fit an LTX. I also know they will let you return it if it's not what you need! Andy
If memory serves me the Mono had 2 different release buttons. One was .530 and the other was .576 wide so it has to fit your release button.
thanks, my LTX has the smaller release button. not sure if this trigger will work with my button. will do more checking.
