S&w 19, 27, 28
You want to be careful about enjoying S&W's so much...you will have a GREAT time, but will be constantly broke (personally, I can live with both options!):bthumb: .
The model 19 is a K frame gun (mid size, per se). Many people think that the K frames are the perfect size, weight, etc. However, if you are planning on shooting a bunch of magnum loads through the weapon, there are some concerns about the frame holding up to the long term (and I mean pretty long term) pounding generated by magnum loads.
The 27 and 28 are N frames (largest size frames until the X frames came along). These will handle all the magnums you care to shoot (I own one of each and have shot a LOT of magnums through both without even a hiccup). Essentially these two model are the same. The 28 (Highway Patrolman) was an economy version of the 27. IIRC, the 27 has more and finer checkering along the top strap and has a WONDERFULLY deep blued finish. The 28's finish is a dullish blue. Additionally, the 27 offered a nickel finish and, I believe, could be had in more varying barrel lengths than the 28. FWIW, the 28 was supposedly offered in nickel for a run of less than 100 (IIRC).
Hope this helps,
Don
