I do gunsmithing on the side for friends and family only ! Have worked on several high quality revolvers over the years, mainly Smith & Wesson and Ruger, a guy brought me a pair of Heritage Rough riders that he disassembled to refinish, he couldn't get the cylinders to go back in. turns out didn't have the firing pin housing back far enough and there was interference with the cylinder, pretty simple fix, I noticed he shaved some metal off counterbored hole for firing pin guide when inserting was the reason for not seating down all the way. Upon further inspection these cheap revolvers are nothing more than pot metal, very low quality. I would never own one of these worthless revolvers. There is a reason they cost under $150. My advice is save some money and buy a Ruger or S&W. one you can pass down for generations not one of these that will end up in a dumpster.
