Might just need some oil. I recently traded for a NIB Classic Model 27. Out of state trade so I wasn’t able to check out the gun, but it’s a new gun so I wasn’t concerned. Had one of the worst actions I’ve ever felt with any brand. Started to send it to the Mother ship but decided to peek inside. Dry as a bone and had a few slightly rough areas. About 5 minutes with a piece of fine sandpaper and some Lucas Gun Oil and now it’s very acceptable. It was obviously assembled with no lubricant at all. Never seen this before.
