I recently bought this 637. It has one range trip and shot great. Being a custom shop gun it has the smoothest DA I have ever felt on a J Frame. I swapped the grips shown for a set of simple rubber two finger groove S&W grips. I have been pocket carrying it. I have yet to install the plug sitting on my bench.
