Let me see if I understand.
- you had trouble with your 582 stainless, which you spent years waiting to be able to buy
- you sent it back and Ruger worked on it
- it came back but still had problems
- you took apart your 581, compared it to your 582, which you had spent years waiting to buy
- you took your Dremel and did some grinding on the oprod
- it worked and then after a while had a half inch of bolt slop so you called Ruger and they told you to ask for a new rifle
- Ruger worked on it, installed a new bolt, not a new rifle
- it fired for 62 rounds but now the firing pin is broken
- Ruger sent you a mailing label to send your Mini back for the 3rd time
Is that about right?
