Hoser, I read through the critiques on the other site and you will find similar here. I own one and let me give you my personal experiences.
Fit and finish. Not real good with regard to wood to metal. However, about what one would expect to see on their recent O/Us. My gun is on the face, flex gap seems just about right and the tubes and rib seem set up without any serious issues. The wood on my gun is very plain.
I shoot double triggers and single triggers equally (I simply don't notice them). However, given a choice, I would prefer double triggers. The GL safety barrel selector design seems to work about as well as any and is better, to my mind, than the trigger mounted push button style.
Everything else is exceptional. Stock deminsions are superior. I have the English stock and I would change nothing on it. The gun, like most Ruger products, seems strong as an ox. I bought it as my utility travel gun, and during the last season it digested a steady diet of 1 1/4 lead loads on Kansas pheasants, dumped geese with authority, and put up fine scores at the clays range using 1 ounce target loads. I even took it out on a box bird venue and certainly did no worse than I usually post with one of my pigeon guns. In short, this is a very useful gun.
I like it's usefulness and shootability so well that, I have decided to make it the basis for an upgrade. It will destroy its "utility" double status, but it should be a very useful upgraded 12 bore. Ken's magic on the action and a nice stick of English to the exact current deminsions should produce a neat product. No, it won't resell for what I intend to put into it, but it will be not only a very useful gun, but also a very unique one as well.
Will ask Ken to post pictures as the project progresses.
