I bought a pair of new Model 60's when they were 1st introduced (I used to be known as "Two-Gun Pete"
).
They both would skip a chamber when triggered/fired fast; so I sent them down the road and got myself 3" Model 37 (no dash) Airweight's instead, which didn't exhibit the same behavior.
I ended up gifting each of the M-37's to my 2 daughters, when they moved out of my house to live in their own homes.
