Welcome to TFL. That serial number would make it 1970. A mint condition P&R (pinned and recessed, which yours is) Model 19 would fetch at least a couple hundred dollars more than you paid in this neck of the woods (eastern Massachusetts).
As you may already be aware, you'll run into conflicting reports regarding feeding a steady diet of .357 through a Model 19. Under certain conditions, it's possible to develop cracks in the bottom of the forcing cone where there's a slight flat spot on K-frame S&Ws. Some folks claim they've run thousands of full-house .357s through theirs, others claim problems from the first few shots. There must be some truth to the issue because S&W subsequently developed the slightly larger L-frame (Model 686 and similar) which avoids the need to have the flat spot.
One seemingly consistent theme is that problems are more likely with hot 100 and 125-gr loads, and if leading is allowed to develop in the forcing cone area. If you really want to shoot .357, the 158-gr loads appear to be the safest.
I have a 19-2 from 1963. These guns are becoming increasingly harder to find at anything approaching reasonable prices and replacement barrels - really the only fix for a cracked forcing cone - are also becoming scarce. My gun sees .38 Special just about exclusively, actually .38 Special loads in .357 cases, and I save the real .357s for my L- and N-frames. Others may feel that's being too careful, but as long as I have other guns that are more suited to the hotter cartridge I'll "baby" my fine old Model 19 and expect it to outlast me.
