I have a very early one, #00014**, and it jammed so tight on it's very first round that it had to beaten clear with a rubber mallet. Seriously. The forward portions of the bolt runner guides appeared to be machined with a wood rasp. The gun was new, and the bolt was still blued. I spent about 2 hours with a flexi-Dremel polishing, and she has rattled through about 6 boxes of shells, now. She's fine, and I have no intention of getting rid of her. Might also add that I have traded for a Taurus Thunderbolt. Might be that I simply enjoy the "trouble-makers?" haha!
