“My brand new gun is jamming!” And not in a Bob Marley kinda way. Ask anyone who works at a gun range: they’ve heard that one before. As Wayne from American Firearms School attests, the lube used to protect a gun before it’s shipped from the factory is not the same gunk you need to keep it running smoothly. So Wayne field stripped and cleaned our recently received Ruger SR40 prior to its test and review (writing it now). Thank you Wayne.
