I just purchased this new revolver, S&W 637 Power Port Pro Series. I've typed a few notes on the photo.
Basically, when I point the barrel downward while opening or closing the cylinder, the edge of the cylinder doesn't bind up where the silver line/groove is located.
When I have the barrel point upward and either close or open the cylinder, the cylinder's edge binds (overlaps) where the silver line/groove is located, and the cylinder becomes difficult to close.
Please advise. Thanks in advance.
