The only change in my update from 4 years ago is the 638 is occasionally replaced with I believe is a 1974, blued Colt Agent. I wanted that extra round for a lounge around gun. Probably sell it soon since even with the extra round it is not a +P capable revolver and I sure do not want to beat it up with maintenance, parts and repair somewhat problematic.
Also...the pair of Belgian Malanois are still trashing my oldest sons home.
