I bought my first Model 28 about 1974, as a college student working his way through school. I got hooked on S&W revolvers immediately, still being so hooked almost 40 years later.
New 28-s were about $159.95 retail. You could buy very nice used ones for less. At the time, the sporting goods chains and many gun shops had lots of S&W accessory and upgrade parts packed in bubble pack cards, either hanging on twirling wire display racks or peg-in-hole display boards on the walls. You could buy new S&W hammers and triggers of all sorts, rear sight blades and entire assemblies, stocks moon clips, magazines, all sorts of things. One local gunshop and a couple of chains carried new presentation cases.
I bought new and used Highway Patrolmen as I found them. I spent hours cleaning each gun I bought. Doug Larson, owner-operator of 'Doug's Sports Chalet' taught me how to cut the front sight blades and install colored plastic inserts to look like factory jobs. I would add a target hammer and trigger, a cut-down rebound spring, smooth out the rougher contact surfaces on the lockwork and frame and sideplate, white outline rear sight blade and a pair of Goncla Alves target stocks to the gun after giving them a real good cleaning. Occasionally, I found nice Magna stocks in colorful Goncalo Alves instead of the normal walnut, or sometimes a buyer wanted rubber Pachmayrs instead of S&W wood. One brand of touch-up blue, a sort of a paste, did a good job on wear spots like front sight blades and sides of muzzles and cylinders. I'd buy some presentation cases and carry them around at gunshows with the guns. I could cover my expenses of buying and accessorizing the guns and make $100 each profit, more of they wanted the wood case. It was a profitable hobby. Even at my price, my guns were a bit cheaper than the then-scarce Model 27. Sometimes I traded my glitzy Highway Patrolman for other guns I wanted. The extra cash and the trades helped me to build my own meager, budding collection faster than if I was just buying with wages.
In the woods, it was rare that I ever holstered any of my Model 27s for woods walking or hikes through the trees or sagebrush, usually having a more workhorse Model 28 with the same shooting capabilities without the same fear of marring that perfect Model 27 finish.
