Saw your post over on the Colt Forum . .
First, I don't think any "clone" is ever going to be 100% copy of a real Colt . . . but they aren't the price of one either.
I like "historically correct" firearms as well - have for 50 plus years . . but just remember . . . you get what you can afford, shoot it and enjoy it.
I have quite a few vintage revolvers - I have always been interested in the 45 Colt Cartridge because of the history of it. I have a 7 1/2" steel Ubberti Cattleman on the way. I ordered the late frame as I just don't want to mess with the BP frame cylinder pin retention screw. But that's a personal thing.
I am older and at this point in my life, it's foolish for me to buy real Colt SAA whether it be 1st, 2nd or 3rd generation. I could afford a 3rd gen. but why? Just to say it's a "Colt"? If I were younger by about 40 years, then I might want a Colt but in those days, I couldn't have afforded it.
I went with the 7 1/2" pretty much for the same reason you want one. More traditional as far as the first ones made - plus - I had an ancestor at the Little Big Horn.
I have a Uberti Bisley. Before buying it, I discussed it with the LGS where I have purchased a number of firearms. As the clerk I've dealt with for years said, they are about as close to a Colt as you'll find and in his opinion, many of them that have come through their store actually felt better - in his opinion. I have no complaints about my Bisley. Yes - it is somewhat "different" than the original Colt version - but it is a real pleasure to shoot and is very well made. I expect none less on the Cattleman when it gets here.
I'll go out on a limb here and will say that I was a little disappointed at some of the replies you got on another site - but most of them are "true Colt" people - which is fine. If you go with a Uberti (which Cimarron is) and somebody wants to stand back and "nit pick" it - let 'em. You'll still have a good shooter that you can enjoy and which will give you a good "feel" of the history of what it's modeled after. IMHO . . . some folks worry too much about barrel markings or perhaps the incorrect shape of the ejector end - and that's not meant as criticism or to offend anybody - we all haver our "thing".
My point is . . just don't "over think" things, worry about what others think or what they would do or if a Uberti isn't 100% exact as far as a copy. Get what you can afford without putting a crimp in your other $$ obligations, shoot it and enjoy it. That's what it's all about. Others may disagree with me and that's fine.
It's sort of like this . . Uberti or Colt . . Ford or Mercedes. In both cases, one will cost a whole lot more than the other . . . but they both will get you to your destination.
Best of luck to you and enjoy whatever you get!
