Very nice! You will enjoy that gun for the rest of your life, not only because it is a sweet shooting Smith & Wesson Model 19 Combat Magnum and can drive tacks all day long, but because it is also your first handgun.
My first handgun was a Model 19 with 4" barrel just like yours only mine is in blue, not nickel. Bought it in 1980 and it is still the gun I shoot the best, and I'll never be without it.
