Here's one that I picked up a few years ago. It is a Model 1877 Colt that has been converted to .22 rimfire from .38 Colt and has had an SAA style grip added along with ivory stocks. It is a SA/DA action (like the original). It still loads and ejects like an SAA, has sights like an SAA and even has a "plow handle" grip like an SAA! But, having been originally a Colt Lightning, it is about 10-15% smaller than a "real" SAA! And, it is a "hoot to shoot"!
