Hi everyone, First of all I would like to apologize about my english. It's not my native language. I just bought a brand new Ruger MK3 Target with an old Serial (227-59xxx) a 2007 model. yesterday night, I shot around 200 rounds with no real problem : only 3 feeding problems. But when I came back home and I look at it, I notices a little scratch in a piece of metal (the barrel or extractor I don't know). Here the pictures (you can click on them to enlarge it) : It look like the loading chamber as been scratched What do you think ? Is it a known problem ? Thanks for you help ! Mike.
