I'm about to return a 2018 model I just received from gunbroker. First range trip and 5 of the 8 factory loads had difficulty extracting (3 of the 5 loads locked the cases in TIGHT). Two loads extracted with minimal bind and Hornady was the only brand that extracted normally and they were the 2nd to last load I tried, so it wasn't a dirty chamber issue.
Broke my own rule of not buying proven used Rugers and have to use Ruger CS again. The price was fair and I'm sure Ruger will make this one right like they have every other gun I've sent them. Called them this morning for an RMA, but they are closed for the holidays. No worries, we're busy too, so I'll try again next week.
