How do you remove the cylinder from a navy colt?

Answer 1

It's not as hard as you may think. There is a wedge pin just ahead of the cylinder, held in place by a screw on the left side. Remove the screw, and tap out the wedge pin with a non marring hammer or wooden dowel from right to left. Some models have a spring within the wedge that will need to be depressed while driving out the wedge. Once the wedge is free, the barrel may be wiggled free or the two alignment pins on the frame, located at the front of the frame near the cylinder ram rod. Once free of the pins you can remove the barrel towards the front. Half cock the hammer to dis engage the bolt from the cylinder, then slide the cylinder off to the front. I have provided a link in the related links section that may be able to help.
