An area of extreme disappointment was the X-Mark Pro externally adjustable factory trigger. Known for its recall (AD) and pot metal like build quality, it is plagued with issues and to say at the very least, it left quite a bit to be desired. To remedy this issue, I installed a Timney Calvin Elite Trigger. This trigger is so nice it warrants a write up all its own. Stay tuned for an immediate follow up article on this finely made trigger!
