Howdy, i just bought a brand new smith and wesson model 27, 4" blue. Ive never owned revolver but one thing i noticed upon handling it, was that whenever i pointed it up or down, there was an internal clicking sound like a loose part. it sounds like its coming from the area behind the cylinder/ infront of the hammer. I figure its normal, but i just want to be sure its nothing fualty with the pistol. any help would be appreciated. Thanks! Nick.
