I just bought a used revolver, fired it on double action when I bought it but am having a single action problem that I was looking for some help with.
The firearm is a Smith and Wesson 329 PD. It fires fine when firing double action. The problem is when the hammer is cocked back and you pull the trigger. When pulled the trigger releases the hammer but the trigger does not stay at the back of the trigger guard. It slams your finger forward with the force of the hammer coming down and if you don't come off of the trigger fast enough it will not fire the round. It would appear it is not firing the round because the weight of the hammer is on your finger and not the strike for the pin.
Also, if you have the hammer back and you slam your finger into the trigger, with alot of force, the trigger will stay back and the hammer fall normally. If you pull the trigger normally it won't cut the trigger loose from the hammer but will cut the hammer loose from it's lock throwing your finger forward
My understanding is that when I pull the trigger, it should stay back till I release it with my finger and it resets for the next double action trigger pull. Is that right?
So that's the problem, any ideas would be great. I asked the place I got it from to try and find out if they knew of any trigger work done or if they knew of the problem. Thought I'd see if anybody here had any ideas of a quick fix or what's wrong. Thanks
