I am looking for guidance (searched but didn't see much on it)on the acceptability of testing a revolver for hammer push-off. In a private sale, I would say that it should be done by the prospective buyer. But I witnessed a bad scene when someone tried it in a LGS and he was accused of possibly damaging the firearm. Equally, I had to take a Model 18-3 to a smith to have it corrected when I did not test for push-off. With pricing in the $1,000 range for most S&Ws in my current target zone, should I just take the chance on a $70 trigger fix?
