When the tax refund comes I will be buying one. I've found one in .45 Colt with 5" barrel and nickle plate. The pearl grips will have to go away and be replaced by ivory eagle & shield grips.
Never had one, but one drawback, at least from my point of view, is that they will bind up rather quickly if shooting BP through them. A Big Lube bullet will help them keep rotating, but even then they need to be wiped down every other stage or so, if you're shooting black.
