After installing a Glockworx race connector and competition spring set on my G26 gen4, I find that my trigger has an annoying notchy feel and audible click right on the initial press, before there is any movement. After overcoming that snag, the rest of the trigger pull is smooth through the break. If I release the trigger only to the reset point, the next pull does not do this. If I release the trigger all the way, the problem recurs. Where should I look to diagnose/fix this problem?
