Hi everyone, I'm new here and in need of some help.

I have a 111 in 30-06 without the accutrigger. This past weekend I was at the range with a friend and was having problems getting the safety to engage. With the bolt open I would insert the magazine and then close to the bolt, chambering a round. Then when I would try to move the safe to the on position it was stuck, this happened a few times and opening the bolt and closing it once or twice would allow the safety to go into place. Except for one time, I couldn't get it to move and when I closed the bolt the gun fired. Luckily were always safe and other than scaring the daylights out of both of us, nobody got injured...or worse.

So my question is what is causing my troubles and what can I do to fix them?

If it matters it was cold outside, probably about 28 degrees and I had fired approx. 25 rounds that day before I started having issues.
I bought this gun used about a year ago and as far as I know, it was never taken apart and has never had the trigger adjusted.

Thank You
