Inspect a 66 police trade in very carefully. Especially the top strap. It may be one that was carried much and shot little but it could also be a heavily used weapon depending on the training regimen. The 19 and 66 were never designed for a steady diet of 357 mags. When some departments started training with duty rounds the guns started having problems. This is why the 686 was bought out.
