I bought my 597 .22LR new about 2 months ago and was finally able to shoot it this past weekend. I fired one shot and experienced the jamming that now seems to be commonplace with this weapon. After 20 rounds and about 5 jams, I put it back in my case.
When I got home I decided to take apart the weapon, and it looks like I got a Friday afternoon/Monday morning gun. The front bolt holding the barrel/receiver/trigger housing had a flat spot on the threads. Great. When I got everything broken down, I saw a small hole on the bottom of the bolt. It was in the bottom of the right groove, about 1/2 " away from the front. Almost looks like there was a small blowout because the hole doesn't look machined.
So, has anyone else had this problem? If so, was there a fix or did you just go with it? If there was already a thread on this, just send me the link because I was unable to find it.
