I've gotten back into black powder recently and was taking a look at a pietta 1858 New Texas Army .44 revolver I have. Now, I am no gunsmith but I have successfully worked on other firearms (and enjoyed it). I was checking the timing and noticed that when I go from half-cock to full cock, the cylinder doesn't always lock up. It has to be slightly rotated a fraction to lock in place. I've been researching this and appears it might come down to the hand or pawl. Would this be accurate?
