Mykeal, the smokeless powder frame has the spring type screw that's located just forward of the cylinder. You must press this and hold it down in order to remove the base pin (cylinder pin) to take out the cylinder from the frame. You have to use a screw driver to remove the base pin screw which is located on the front of the frame just below the barrel on the black powder frame. Many guns have their threads damaged through careless tightening, which then requires an oversized basepin screw.
