I had a real early 4" M66 and granted, it was nice to look at just not to shoot. Very loud and at 4" long the barrel should have been 6" or longer as a hunting gun. Then a M629 6" Classic replaced it and that was better. The Wisconsin State Patrol carried 66's for a time, but scrapped them for semi autos because they were shooting lose with magnum .357 loads.

My other auto is a .45

The bitterness of poor quality is remembered long after the sweetness of low price has faded from memory
