They are a good, serviceable revolver. Use a coil spring action instead of the the leaf used in the Python and earlier Troopers. This was brought in because of cost of the Python and it's action fitting. Available in 22 LR, 22 Mag and 38/357, with barrel length of 4", 6", and 8". Three finishes (blue, Coltguard, and nickle). There was also a fixed sight version called the Lawman, which was available as a snubby. Colt also sold these as Border Patrol models, with no actual difference to the revolver that I have ever found, except the rollmarking on the barrels. FWIW - dan
