I have always wanted an 18 S&W Combat Masterpiece 22 LR and never saw one to buy. I used to see model 17's but never 18's. A friend had an 18-3 and a 17 which I got to shoot. One day I was in a gun shop in Kentucky and they had a model 18 no dash in 85% condition with box and original diamond grips. They had it marked at $425. I asked the owner if that was the correct price and he said that was an accurate price according to blue book. I couldn't get my money out fast enough, the revolver had holster wear but had not been shot much. I intend on this revolver being a family heirloom but I still enjoy shooting it and just owning it. I bought a Taurus Model 94 thinking I'd never find or be able to afford a Model 18. I guess I just lucked out and my serial number indicates my model 18 was made in about 1955.
If you ever see a 17, 18 or 617 you have to jump if the prices are decent because they won't stay on the shelves long. The gun shop put the model 18 on the shelf the previous afternoon and I bought it around 10 AM.
