I recently received my Umarex co2 Colt Python full metal revolver. I started noticing the cylinder was acting funky each time I pulled the trigger, and then I found out that the cylinder releases after pulling the trigger a couple times. Besides that, the trigger itself does not instantly go back into place after being pulled, it will either stay there for a couple of seconds then "click", it's back into place, or it will just stay there unless I push it forward to click back into place. What in the world is going on with this thing? And is there a way to fix this?
