I was told by a guy that if someone changes a flash suppressor and does not change the crush washer. that gas could leak out .

Is he pulling my leg?

He's either pulling your leg or he is an idiot.

My guess is he's an idiot!

Yep. He definitely is that.

This same expert now informs me that I cannot simply snip off a coil from the rebound slide coil spring in order to do a trigger job on a S&W revolver. Instead I need to buy springs from Brownell's.
Sheesh!
