Well, flame-cutting and cracked forcing cones aside, the Model 19 was the perfect size, weight and balance for a police duty handgun (it was my first in 1979). It was also quite accurate (with the right loads), and if not fed a steady diet of full-house magnums, proved durable and reliable enough.
It was the abuse of the Model 19s with the faster lightweight 125-grain JHPs when they came out that contributed to a lot of the issues this revolver suffered.
We trained and qual'd with .148-grain .38 SPL LSWCs and carried 158-grain magnums.
I have a couple of these dating back to the '60s that still lock up tight, no cracks, that I'd trust my life to.
