I purchased another Python a few months ago and have only fired a few rounds out of it, without any issues. However, twice now it has gotten out of time or had some kind of problem with the action while operating the hammer/trigger at home. What will happen is I will cock the hammer and pull the trigger but instead of the hammer falling, it will go to half cock and then the remaining spring pressure will push forward on the trigger, releasing the hammer at the same time. I hope I am explaining this correctly. I have other colts and revolvers... I've never seen a pistol do this before. I am hesitant to take the cover off myself, as this is a pretty valuable pistol. Do you guys have a recommendation for a gunsmith?
