I have since learned a bit about S&W revolvers. I had seen people refer to their Model 19's as "19-2, 19-3, 19-4", ect. but I just read over it without understanding it. Then I began getting people asking me if my revolver was a "19-5", so I had to profess my ignorance and ask them; "huh"? It turns out that through the years whenever S&W made revisions/improvements to the Model 19 they would denote it by adding the hyphen and then the revision number. It turns out that mine is indeed a 19-5. I also discovered that the proper name for this revolver is S&W Model 19 Combat Magnum chambered in .357 magnum. Finally, it seems as though the S&W revolver that I carried as a Military Police Patrolman aboard NAVSTA Mayport must have just had a really BAD trigger, as I'm hearing that it's likely that no work has been done on the trigger on my Model 19 other than a proper amount of use. I learn something every day...
