In the 18 years I have been repairing firearms there has only been 1 that I couldn't repair.
What kind of problem are you having?
Sorry, I missed the "What have you tried"
Are you referring to the pin that holds the shell latch in place?
I will not be available for a phone call until late this afternoon, sometime between 4 and 5 pm. (eastern time)
My power has been on and off the last 8 hours due to a huge snow storm, over 3' and still coming down. My phone is thru the internet and I loose connections when the power is out. Cell phone reception is terrible right now.
I will try tomorrow if it's okay with you. Let me know a time that is good for you.
