Take the slide off and see if the trigger/hammer works normally. Use the palm of your hand in front of the hammer to ease the hammer forward when/if it releases normally. Basically it lets you know if it is the FCG or an issue with the spring/firing pin block button thingy on the bottom of the slide. If the spring for the firing pin block binds up it can cause issues similar to what you describe.

My FNX 40 did that when I put new sights on it. After removing the sights again and fixing that spring placement it worked fine again.
