Hey all, I was field stripping my MK II for cleaning tonight, and as you can tell from my message title, I didn't get very far. The bolt only comes about halfway out of the receiver before stopping abruptly, stopping just before you can see the spring. I cleaned it once prior to attempting this time, and the bolt slid right out. This is a fairly new pistol, with only about 300 rounds through it. It may not be related, but I had three stovepipes today at the range late in my session, which I had chalked up to the breaking-in process. After trying a few times, but not wanting to force it out, I just put the mainspring back in and the pistol seems to be fully functional. The bolt moves fine. Also, it was cold (Michigan, brr) at the range--I don't know what difference that makes, but I wanted to be as specific as possible Has anyone had this problem? Any particular conditions that spring to mind?
