I thought that I had been to the mountain and saw the elephant, but a bulged cylinder? I really didn't even think that was possible, that the cylinder would crack before it bulged. If you have a bulged cylinder, then apparently I was in error. Maybe you should get a second opinion, JMHO
There's no need for a 2nd opinion when the problem is determined by one of the best gunsmiths in SA with over 30 years of experience.
The whole gun was checked, only problem is the cylinder.
Thanks to all,
I've managed to get a full set of spares from S&W.
