Hawk makes some good points and no, I don't believe he has an axe to grind. He's just telling it as it really is.
I love S&W, or at least some of it. I was literally raised on S&W handguns. My father had an old 6" Model 10 that he and my mother helped me hold as a child and learn to shoot on. Mom carried a Model 36 in her pocketbook, most of the time. At 14, Dad gave me a M-10 he bought from a guy at his job for a good price and at 16, he gave me his 6" M-28, that he had been wearing as a reserve deputy in our home county. He had acquired a Colt Trooper with a 4" barrel and it was an easier carry on his duty belt, although Dad still liked S&W's grip frame and action better, as did I.
Back in 77, I purchased a nickel plated M-36 with 3" barrel and round butt. It was a great little gun, with great accuracy. In 1980, I purchased a 4" M-29, the answer to a long dream of having one of these great guns. It had issues. One was that two chambers (I actually was able to verify which two) would print practically on top of one another at fifty yards. The others, were all over the target. This was during a period when S&W QC was really in the toilet. I sent it back, asking that a new cylinder or whatever the issue was be corrected. About three months later, I received the gun, with the same cylinder and the same problem. I later sold it to a friend who, even though warned of the issue, wanted the gun worse than I did. In 1988, I thought I had found my dream duty weapon, a 686 with round butt. When I went to shoot it after purchasing it, I noted that it was shooting waaaay to the left, even with the rear sight blade adjusted so far to the right, that it was hanging over the edge of the track the blade was seated in. A friend who was with me had the same problem. Our best groups were about eight inches to the left at 25 yds. Upon cleaning the gun at home, the problem became apparent. It was a large tool mark in one of the grooves extending from the muzzle back, about a half inch. A trip to S&W with a note that it was a police duty gun saw it coming back in about two months with a new barrel. It grouped fine but now, the rebound spring on the trigger had something wrong and if you were dry firing it, the hammer might not rebound at all if you let your finger off of it slowly enough. I traded it shortly afterward for a 4" Ruger Security Six.
In 1992, I purchased a M-640 (the TRUE j-frame in all stainless). It was great and I lost it in a divorce settlement. :-(
In 2007, I helped a female friend to get her CWP and bought her a 640 (the steroided .357). It was reasonably accurate but after less than a box of fifty rounds, the trigger was exceedingly hard to pull. I took it home and cleaned it up and it worked just fine. The next day, when she had to go for her CWP range test, she said it was doing the same thing, again. I took it home and cleaned it and found the problem. The gap between the cylinder and forcing cone was so narrow, that firing just a few rounds put enough crud on the cylinder face to cause it to bind up. Sent it back to S&W for that to be fixed. It came back in less than a month and worked fine. The day we sent that one back, I bought her a 642 so she wouldn't be without a gun while waiting on that one to be repaired and also, so she had one that was more easily carried concealed. As I explained to her, she needed to have at least two because the police would confiscate whichever one she used, should such an unfortunate event ever unfold. The new 642 worked just fine, but I noted that on her 640 and her 642, the bore had an exceedingly cruddy finish in them. The clean, smooth, lands and groves of past S&W's was not there. Instead, the new guns' bores looked like some sloppy workmanship or tooling had been used in the process of rifling the barrel. I just read elsewhere on here where S&W has gone to some electro-chemical process to rifle its barrels. FWIW and IMHO, they look like crap and don't clean easily as the old ones did.
Issues with the lacquer coating on the frames of the 642's are widespread. I later purchased two 642's for myself and was disheartened to find the frames had that crummy lacquer on them which can and does peel at times. Why didn't they just anodize the frames instead of using that lacquer?
I have a 442 on order, one without the "Hillary hole". I hope it will be a good one, reliable, accurate, and with a better bore than others I have seen.
Hawk was just telling the truth. I love some things about S&W, but they have had and probably still do, much room for improvement.
