I am looking to purchase my fist S&W revolver for myself, at this point I think it will be a Model 19. I picked up a 4" barreled Colt Trooper Mk. III (I consider them to be very underrated) and want a nice S&W to go with it, so I am looking at 4" barreled Model 19's. I really like the size of the M19 and considering how I will be using the pistol I think it would be a good choice. I primarily shoot auto-loaders so any 19 I purchase would see about 100 rounds at the most each year, with maybe 25% of that being 357 magnum and the rest 38 special. Now back to my main question, should I look for a 19-3, or 19-4? Does the 19-3 offer any advantages over the 19-4?
