Some of them seem to have a reputation for having problems with the barrels peeing. Others with them seem to not report this problem so not everyone seems to have it. It's just enough of them that do have it that it makes me weary. However, Ruger has great customer service. Some of the best I've ever dealt with or even really read about. I wouldn't hesitate to buy most Rugers but just be aware that it may peen some. IMO for a range gun they are good. For a carry gun I think I'd chose a Glock instead. Or a old P series Ruger which are pretty much known for being super reliable.
