TacPhoto..... Congrats on your new purchase -- you're going to love it!
For others who may be considering the same two models, a good way to do the 27 and 28 comparison is to look at the way most of these guns were commonly delivered, especially the earlier P&R guns.
The 28's were delivered with a matte blue finish and a 4" or 6" barrel. They most commonly had magna style grips that were standard and many came in the traditional S&W blue boxes...
The 27's were delivered with a bright blue or bright nickle finish and barrel lengths of 3 1/2, 4, 5, 6, 6 1/2 and 8 3/8" barrel lengths. Most have target triggers, target hammers, target Goncalo Alves stocks and came in a mahogany presentation case typical to their mfg time period. They also possess the beautiful checkered top strap and rib that no other N frame model can claim.
The presentation cases, tools, stocks and target features have collector value all their own and those additions can add substantial value to a 27 that is complete with all those features...
The 28 is a bare-bones, "best bang for the buck" work horse that does everything its "princely" brother can do as far as having N frame ruggedness, durability and shooting. The 27, however, does it with a visual style and and a special appeal that causes many to choose to define it as "the finest S&W ever made."
Either model is a great choice. It simply depends on how you want to use it and what your preferences are... Both have a huge following.....
