You did not say if you let the hammer fly off full cock when you pulled the trigger or eased it forward. If you let it go on it's own, you most likely damaged the hammer and/or sear or any of the associated springs. Do not dissasemble the group, you probably won't get it back together. Take it to a gunsmith and he will check the hammer, sear, disconector and springs.Don't take him a bag full of parts (have had many come to me like this), you will be charged extra. Hope this helps..
