I have begun carrying my model 60 again from time to time and have been reading with interest about the +P controversy.
I was a Treasury agent during the time when we were armed with revolvers and carried revolvers as off duty weapons. The .38 special was the only authorized off duty weapon and many carried SW 36s and 60s. We were required to fire 30 rounds of standard issue +P+ quarterly for a total of 120 rounds per year. No one ever had a failure of their 60 or 36 with a round hotter than any +P. I think the issue of not firing +P on a regular basis is a bit over done as the +P+ did not present any issues with the J frames.
