i recently upgraded to hard chrome but my first combo had peening issues so i returned it to kel tec. the replacement they sent me had this weird mark just in front of the ejection port on the top of the slide where it looked like bare metal like it had not been finished i called KT they explained to me this was a mark from the heat treat process and if i wasnt satisfied i could exchange it for another. the only problem was the replacement i got had the same exact mark on it so i called again, then they told me that almost every slide has this mark and if they didnt then it wasnt properly treated. long story short it kinda bugs me has anybody else had this issue
