Heading to the range today and the 200 rounds I am going to put through my SR9c will be bringing my totals close to 1000 in a month. It got me thinking. At this pace I will have 12,000 rounds through my gun in a year. I don't expect to keep this pace up, but if I did, at what point will I need a rebuild or replace my gun? Since I can't get a barrel from anyplace but Ruger, how many rounds is a barrel good for? Does it all come down to care and cleaning?
